What Is qFIT?

qFIT is an activity tracker — but really it's a motivator. The Checklist and To-Do list are dynamic: they highlight what you should do first to meet the goals you set. Keeping that list short feels a little like a game.

What we're trying to help you do:

  • Make fitness easy and fun — and actually doable.
  • Do lots of healthy things every day and every week, not all at once on certain days.
  • Get out of the rut, break old habits, and try a wide variety of things.
  • Reach your goals without planning or thinking — just check boxes.
  • Turn the occasional healthy day into a healthy lifestyle.
  • Replace some gym time with sports and activities that are more fun.
  • Stay active, stay young, and work toward reversing pains & injuries.
  • Keep challenging yourself with small goals you'll actually hit.

By the Numbers

qFIT works because it already knows what there is to do. You are never asked to invent a workout — you're picking from a catalog that was built, written up and cross-referenced before you arrived.

🏋️ 5,000+ exercises

And not just names on a list: every single one carries step-by-step how-to. Nearly all of them also carry background detail and the other names the same movement goes by — so you'll find it however you learned to call it — with links out to more, and most carry our own recommendations too.

🤸 1,000+ activities

In 18 Categories — strength, stretching, cardio, balance, recovery and massage, nutrition, rest, mental health, focus, social, productivity, health and prevention, injury and rehab, sports and recreation, challenges, and weekly, monthly and yearly goals. Fitness here is not only the gym.

💪 23 muscle groups, 30,000+ links

Nine in ten exercises — nearly every strength one — are mapped to the muscles they work, primary and secondary — 30,000+ connections across 33 body areas: 23 muscle groups plus the joints you can filter around when one of them is hurting. Plus more than 600 alternate muscle names, so searching “lats” or “quads” finds the same thing an anatomy textbook would.

🏠 3,000+ need no equipment

More than 3,000 of the exercises require nothing at all — no dumbbell, band, ball, bench, machine or bar. Filter to those and you have a program you can run in a hotel room.

📋 234 ready-made routines

Sequences you can start with instead of assembling one — including routines built to fix the everyday complaints that keep people from training: lower back pain, achy knees, sore feet and Achilles trouble, tight hips, stiff shoulders and a desk-bound neck — and Common Problems names which routine goes with which complaint, across 509 common problems — 150 of the routines are built to help with them. Plus the ordinary ones — Morning, Bedtime, Pre-Hike, Post-Gym and full gym splits. All of them sit on one Routines page, one tap to start; each opens on the handful of rows that matter most, and every row says why it's in the routine. And 7 free calculators (BMI, body fat, calories, macros and more) that need no account.

🎂 62 health checks and habits by age

Health at Your Age, for logged-in members, covers 62 screenings, shots, checkups and habits US guidelines recommend — 26 screenings and tests, 12 vaccines, 8 checkups, 6 prevention steps and 10 everyday habits — each tied to the ages it applies to, with its source and the date its guideline was issued — plus every one of the 560 common problems: the age at which 184 of them become common, and the rest by how common they are.

♾️ And then as many as you like

The catalog is the starting point, not the ceiling. Add your own exercises, activities and whole Categories, rename anything, hide what you'll never do, and set your own points and goals. There is no cap, and none of it costs anything.

📖 67 pages with a built-in walkthrough

Nearly every screen carries its own tutorial you can open with the ❓ button, plus 132 glossary terms covering fitness, training, anatomy, cardio and strength, and inline tips on the pages themselves. Written by hand, not generated.

Screenshots

Checklist screen on a phone. Six color-coded Category rows fill the screen — Focus, Challenges, Weekly Goals, Monthly Goals, Balance and Mind & Mental Health — and most rows carry a large white checkbox, a High priority tag, a tag saying when the row was last done, such as "4 days", and an information button at the right.
The Checklist — every Category you track, color-coded, with a box to check.
To-Do screen on a phone. Under the heading "Strength & Workouts" are three ranked rows — Core, Full Body and Shoulders: Rotator Cuff — each showing a checkbox, an "Our Goal" tag, a "0/3-7d" goal chip, a "NEVER" tag for when it was last done, a link that opens its exercises, and a colored stripe down its left edge.
The To-Do list — what to do next, ranked by what it needs most.
Dashboard screen on a phone. A large "89%" figure sits above the lines "High-Priority Goals: 10 of 11 met" and "Other Goals: 213 of 239 met", each with a "see what's left" link under it, then today's checkbox and point counts, a green progress bar, and a "Goals Still to Hit" line that opens the breakdown by type and priority.
The Dashboard — how many of your goals you have actually met.

Feature Highlights

The things qFIT does that a fitness app usually doesn't. Every one of them is free, several work before you have an account, and Try the Demo on the Home page lets you look around a real checklist before you join.

☑️ One check is the whole interaction

No reps, no sets, no weights, no timer you have to remember to start. You did the thing, so you check the box — uncheck it if you slipped, and an Undo puts back anything you'd recorded against it. Everything else in qFIT is optional detail layered on top of that one action, which is why it survives the weeks when you have no energy for admin.

📱 Your tracks and your watch check the boxes

With qLIVE, our Android app, your recorded tracks and a watch that syncs to Health Connect — Garmin, Fitbit and others — check off your steps, walks, hikes, rides, runs, paddles, swims and cardio minutes by themselves, on the right day, each with a note saying where it came from. Only Targets you show, never one you already checked, and one you uncheck stays unchecked.

📓 Detail when you want it, never when you don't

Behind the one check: log a set at a time, one box per set, up to five; record an amount in the unit you set for that exercise — reps, weight, minutes or miles; write a note against that day, what hurt and what felt good; and time a stretch with a hold timer built into the exercise itself. Every Category, Target and Exercise has its own page with its completion history and streak, and the streak rules written down so you know what breaks one.

🌳 Three levels, so you choose the detail

Category → Target → Exercise. Log “Stretching” as one check on a bad day, or the specific stretch you actually did on a good one. The same checklist works for somebody tracking “did I move today” and somebody tracking forty individual exercises.

🔬 “Arms”, “Triceps” or “Long Head” — your call

Three Muscle Detail Levels — one each for Strength, Stretching and Massage — decide how finely your checklist splits the body: High-Level (Arms), More Detailed (Triceps) or Most Detailed (the exact head of the muscle). Any single muscle can be set to Show or Hidden by hand and keeps that setting when you change a level, and an exercise under a muscle you don't show simply lists under the nearest muscle you do.

🧠 A To-Do list that shows its working

What's due now, ranked by what it actually needs — importance, then how far behind you are, with a muscle you trained yesterday set apart under 🛌 Resting Today and not counted as due — and an explainer that spells out exactly how it decided the order. It is not a black box: it measures against your own goals or, for muscles, our recommended ones for the intensity you've chosen, and the To-Do list and Checklist can both re-sort their rows largest muscles first or A–Z instead.

🔥 A dashboard that answers “am I actually doing this?”

One percentage for how many of your goals you're meeting, each judged over its own rolling window; what's still outstanding, split by type and priority; momentum — this week against last, this month against last; and the streaks and records behind your exercises. Not a wall of graphs. What to do about it is on Home: a randomizer deals you five exercises, one per muscle where it can, from the muscles that are due next, and an Also Worth Doing card turns up only when there's upkeep that isn't an activity — a weigh-in, the days you forgot to log.

🏆 Compete on variety, not volume

Log in and see your last 30 days against your mutual contacts — people you've added as contacts who added you back, on your Contact List or on qMEET or PacklistPRO, which share the same list — on five measures — total activities, different activities, different muscles, different exercises, and every box you checked — plus an all-time board of how much of qFIT you've actually tried. Eight treadmill runs are eight activities but one for variety, so doing more different things beats doing one thing more. Nobody sees what you did, only the counts, and whether yours appear at all is your call — your mutual contacts see them unless you choose nobody.

💤 It notices what you're avoiding

A neglected muscles card names what you haven't worked recently — and you set what “recently” means. Most apps only tell you what you did; the useful half is the part you keep quietly skipping. The Checklist does the same for anything at all: show only what you haven't done in 2 days, 30 days, or a year.

⏮️ Catch Up, for the days you missed

Backfill a day you forgot to log, against the date it actually happened, then drop straight back onto today. Missing three days doesn't have to mean losing the record of them — or pretending they happened this morning. Choose which day a check lands, so a late-night session goes where you meant it, and Home flags the days in the last month that look too quiet — because usually you did the thing and forgot to check it.

🎲 Two ways out of a rut

Try Something New is a hand-picked gallery of activities that aren't on your Checklist yet — one tap adds one, and an Undo takes it straight back — and the checklist's own randomizer picks something for you when you can't face deciding, or picks only from what you've never tried. Variety is the thing that keeps a program alive, and neither of these waits for you to think of an idea.

⭐ Rate an exercise, then filter on it

Score any exercise for how effective it is and how much you enjoy it — then filter your Checklist down to exactly that. “Show me the things that work and that I don't hate” is a real query here, and it's the one that keeps people going.

🔁 234 routines, one tap to start

Every ready-made routine is on one Routines page. Search it — try back, knee, sleep, posture or gym — or narrow it to the most common, the ones built for a problem, the ones recommended for you or your own, or by topic (everyday, healthy habits, pain and rehab, health conditions, sports, gym), then press ▶ Start and your Checklist shows just that routine, in its own order, until you clear it. Each one opens on its essentials, the handful of rows that matter most, and Full shows the rest. Log in and you can ★ star the ones you come back to — they lead the Checklist's Routine list, where All Favorites Combined shows every one of them at once, and Home's Try a Routine card — and a search also reads the problems each routine helps with, so “plantar fasciitis” finds the one built for it though its name never says so.

🩹 Routines for the thing that actually hurts

Ready-made routines you can start from, or build your own — Morning, Bedtime, Pre-Hike, Post-Gym and the gym splits, but also lower-back pain, achy knees, sore feet, tight hips, stiff shoulders and a desk-bound neck. Common Problems, for logged-in members, covers 509 common problems, each with a page of its own — what is going on, the causes, what makes it worse or better, and when to get it checked, and on more than 230 of them the numbers, the common myths, how it's assessed and the research behind it — and for 506 of them names the routine built for it. That is 150 problem-fixing routines out of the 234 ready-made routines in qFIT. A further section covers 51 common conditions and ordinary features of the body that no routine changes, such as appendicitis, hair loss or cellulite, with what does treat each one, or that nothing reliably does, and when to get help, and a last one holds 10 guides to prevention, preparation and safety — getting fit before surgery, ski season prep, keeping up with checkups, massage tool safety. Find yours by body part or area of life, or in everyday words like “sore” or “hurts”, and + Add to My List on the ones you have. Every routine doubles as a one-tap filter on your Checklist, and with a ready-made one on, each row carries a line saying why that routine includes it.

🧩 Tell it what hurts; the checklist reshapes itself

Check the everyday problems that apply to you — a bad knee, poor sleep, a desk-bound neck — on your profile, or with + Add to My List on any Common Problems card or problem page. The list is optional and completely private: no one at qFIT looks at it, it's never shown anywhere or shared, and it's used for one thing only — suggesting routines to you. Recommended for my problems then pulls every routine matched to what you picked into a single list, Targets and Exercises together, one tap from your Checklist, the top of the Routines page and Home. Pick nothing and nothing about qFIT changes.

🎂 What's recommended at your age

Log in and Health at Your Age lists what US guidelines recommend for someone your age, out of 62 screenings, shots, checkups and everyday habits — from a blood pressure check to a colonoscopy, a mammogram, the shingles vaccine or 150 minutes of activity a week — each with its source, the date its guideline was issued, and what to ask your doctor, gathered into one list of questions you can print for your next checkup. Beside them: which of 184 everyday problems become common around your age, the routines worth starting before they do, what's coming in the next five years, and the other 376 common problems, which are not tied to an age. Put one on your To-Do with its real schedule, from 5 walks a week to once every 10 years, and log when you last had it so it isn't shown as overdue. Tap + Add to My List on the ones you want to keep an eye on and one tap shows only those, even the ones that belong to another age — and ☆ any routine it suggests to make it a favorite. It never asks about your health — things like smoking appear as “If you smoked…” lines for you to read — and a card on Home flags each birthday that brings something new.

🚫 Track what you shouldn't be doing

Mark a Target as a penalty and the checkbox changes meaning: it's now the thing you're trying not to do, and checking it can take points off your day. The habit you're breaking gets tracked in the same place as the ones you're building.

🎚️ Goals without filling in dozens of numbers

Pick your Fitness Goal / Intensity (Bare Minimum, Moderate, Aggressive or Extreme) and every section fills in, with a recommended goal for each muscle. Before anything is rewritten you see exactly what's about to change and confirm it — and a bulk save you didn't mean can be undone.

🟣 The whole priority system is one color

Magenta means a goal isn't met yet. Do those first; everything else can wait. Goals read as “3 times every 7 days” and the window rolls — always the last 7 days counting back from today, never a calendar week that resets on Monday — so starting on a Tuesday doesn't waste a week. The built-in Weekly, Monthly and Yearly Goals Categories are the one exception: those use real calendar periods.

⚡ Change fifty rows without a Save button

A spreadsheet-style grid where visibility, priority, points and goals are dropdowns across dozens of rows at once — and there is no Save button at all: each change writes itself, tells you it saved, and keeps your value in a red cell if it couldn't. Setting up a real program stops being an evening of one-at-a-time edits. And on the Checklist itself, press and hold any row for Quick Edit: visibility, priority and goal in one small pop-up, which is also how a hidden row comes back to Show or Toggle.

🔧 It hides what you can't actually do

Tell qFIT what equipment you have and everything requiring the rest disappears from your Checklist, with one-tap presets for the usual setups. A list full of exercises you have no cable machine for is a list you stop opening. Or turn it round: pick the one piece of equipment you have with you, and the checklist narrows to what you can do with it. Home and the gym each keep their own equipment, and one Equipment dropdown switches every list between them — so the cable machine is there on gym day and gone when you train in the living room.

🤕 Injured? It stops suggesting what would load it

Check whatever you're injured or recovering from and every exercise mapped to that area at all — not just as its main target — disappears from your Checklist, your To-Do list and the Dashboard's suggestions. Deliberately cautious, because showing you something you shouldn't do costs more than hiding one you could. Uncheck it when you're better.

🌱 You never face an empty app

A short setup walks you in rather than dropping you on a blank list: apply a starter set of Categories, Targets and Exercises in one tap, at the level of muscle detail you want — “Arms” if that's plenty, “Biceps Brachii” if it isn't — including a recommended set built to head off the common pains and the muscle loss nobody notices until it's happened.

✍️ Somebody actually wrote all this

Not generated filler: a first-person account of coming back from pain, training tips with the numbers cited, a worked example week, worked use cases, 132 glossary terms and a hand-written tutorial on 67 of the pages you can open with the ❓ button. The reason most trackers get abandoned is that nobody explained the thing you were looking at.

🧮 Seven calculators and a workout timer, no account

BMI, body fat by the tape method, daily calories, macros, one-rep max, running pace and water intake — all sharing one Your Stats card and recalculating as you type, imperial or metric. The timer does intervals, rest and stopwatch with one-tap Tabata, HIIT and EMOM presets, keeps running with no signal once it's open, and holds your screen awake so the phone doesn't sleep mid-set.

❤️ Heart-rate zones, thirteen ways

Not one formula and a shrug. Thirteen published zone models — Karvonen, %HRmax, the AHA split, all three Garmin methods, Apple Watch's zones, Friel run and bike, Coggan, Seiler's polarized three-zone, Zoladz and Maffetone MAF — on top of nine different age-to-max-heart-rate equations. Serious methods genuinely disagree with each other, so qFIT lets you pick the one you actually train by instead of pretending there's only one answer.

📚 Over 5,000 exercises, and your own on top

A catalog where every single one — not a well-documented few — carries written how-to steps, nearly all carry the background detail and most our own recommendations, filed across 234 muscle Targets and 30,000+ muscle links, plus a muscle guide covering the groups people forget. Nearly every one names the muscles it works and the other names the movement goes by, so a search finds it however you learned to call it, words in any order — and one-tap How To buttons search YouTube, Google, ChatGPT or Gemini for that exact movement. Over 3,000 of them need no equipment at all. Add your own, file them where you think they belong, and hide instead of delete so you keep the history.

💪 A muscle guide and an organ guide

117 muscles across six regions, each one saying in plain words where it is, what it actually does and what trains it — and 27 flagged as the ones almost nobody works: the peroneals, the deep hip rotators, glute med, the pelvic floor, the muscles inside your own feet. You can search it by the problem rather than the name, so “shin splints” and “plantar fascia” both land on the muscle behind them, and three filters narrow it to the overlooked ones, a recommended short list, or the muscles no gym machine reaches. Every card opens to More Details — where exactly the muscle is, what a weak or a tight one feels like and, where it matters, when to get it checked. A fold-away card ranks the muscles by typical size, for men and for women, from published scans. Its matched pair, the organ guide, does the same for 40 organs across eight body systems — what each one does, and the habits that keep it working — and every card there opens real Targets and routines in your own account.

📈 Charts that count effort, not just check marks

Activity over the last week, month, year or any range you pick — switchable between counting check-offs and counting points, the effort score you set per activity, so twenty minutes of rehab isn't scored the same as checking “drank water”. Break it down by Category, Target or individual Exercise, save any chart as an image, or download the day-by-day numbers behind it.

⚖️ Weight, waist and body fat on one trend line

Log any of the three against a date — all optional, fill in whichever you actually track — and watch the line rather than a single number. Saving the same date twice updates that day instead of stacking up rows. Private to you, and it touches nothing on your Checklist.

🖨️ Your history walks out with you

A clean printable checklist (or save it as a PDF), a CSV of your Checklist for the day you're viewing, a CSV of your whole tracking history for any date range, and the numbers behind any chart. No export tier — each one is a button.

🔔 A reminder you can silence at ten at night

A daily nudge about your Checklist, or a start-of-week one about your week, by browser push, by email, or both — and the email goes to whichever address you name, not the one you joined with. Quiet Hours silence the push overnight, a one-tap 12-hour snooze kills it for the day, and a test button checks this device can show a notification. All of it off until you switch it on: nothing here emails you because you registered.

🎨 Color-code it so a long list scans in one look

Give every Category its own color and a fifty-line checklist stops being a wall of text. Pick a ready-made scheme, shuffle until something fits, tune the saturation and brightness, or set one Category by hand with a real color picker — the page repaints as you go and saves nothing until you press Apply, so there is no wrong move to undo. Dark mode, text size, page background and which page qFIT opens on are one page over, on Preferences.

🔐 One login for three sites, two-step verification when you want it

Check Use Two-Step Verification on Account & Security and a login from a browser we don't recognize has to enter an emailed login code first. A browser you already trusted on any of our sites is trusted here too. The same account opens qMEET and PacklistPRO, so it's one password, not three. Log Out Everywhere logs out every device at once, this one included, Forget My Trusted Devices makes every other device ask for a fresh login code the next time it logs in, logging in with Google means we never hold a password for you at all, and you can deactivate the account yourself without emailing anyone to ask.

📴 It opens in a basement gym

Install qFIT to your home screen and it opens full screen, like an app. To-Do, How I Use qFIT, the Dashboard and Home are kept on the phone itself, so they still open, to read, when the gym has no signal. The Checklist does too once you press Save This List for Offline on it — the routine you're about to do, or your whole checklist, with the details page of everything on it. What you check off or log with no signal is kept on the phone and sent when you're back. Catch Up needs a connection to load. Press and hold the icon for shortcuts straight to Home, the Checklist, To-Do or Quick Add. And on every guide page, Save All Guides for Offline puts all the guides on the phone, to read with no signal: The Essentials, the Muscle Guide, Organ Guide, Common Problems and every problem page, Injuries, Health at Your Age, Colds, Flu & Stomach Bugs, Fitness Tips, Glossary and Tips.

What You Can Do

🏋️ Strength & Workouts

Build strength with the exercises, machines, sports, and activities you actually enjoy — add anything you like, or want to try.

🧘 Stretching & Mobility

Loosen up, improve your range of motion, and move more comfortably every day — morning, bedtime, or anytime you feel stiff.

💆 Recovery & Massage

Work in self-massage and recovery so soreness and stiffness don't pile up — especially after a hard day.

⚖️ Balance & Stability

Stay steady and help protect against falls. Small daily balance work adds up to a lot over time.

❤️ Cardio & Conditioning

Walks, runs, rides, classes, machines — whatever gets your heart rate up. Pair it with Heart Rate Zones to keep the effort where you meant it to be.

🥗 Diet & Rest

Track the healthy habits that aren't workouts too — eating well, hydration, and getting enough sleep.

🎲 Variety & Discovery

Break out of ruts — Try Something New and the Checklist's randomizer nudge you toward things that aren't on your list yet, so you never get bored.

🩹 Aches, Pains & Prevention

Starter sets aimed at the usual suspects — lower back, knees, feet, hips, shoulders — ready-made routines for 509 common problems, a muscle guide that flags the stabilizers most routines quietly skip, and Health at Your Age for the screenings, shots and checkups due at yours.

How It Works

  1. Build a list in a couple of minutes. The Quick Start wizard applies starter templates and switches on the activities you already do — you rarely type anything from scratch. Or skip the building: pick one of the ready-made Routines and press ▶ Start.
  2. Set your goals once. Tell qFIT what you want — e.g. quads 3 times every 7 days, or the spin bike once a week. Presets fill everything in if you'd rather not think about it.
  3. qFIT shows what's next. Your Checklist and To-Do list put the most urgent thing at the top: a muscle you trained recently moves to the back, then the goals you are behind on, High priority first, then how far behind its own schedule each one is.
  4. Just check boxes. No planning, no thinking — knock out a few things whenever you have a minute.
  5. Watch progress build. The Dashboard and Charts show streaks, counts, points and trends as the days add up — including what you've been avoiding.
  6. Keep it fresh. Add new activities, try something new, and dial qFIT up or down as you grow.

Missed a few days? Catch Up lets you check off what you actually did on days that have already gone by, so your history stays honest.

Tracking & Goals

✅ The Checklist

Your daily home base. Search it, filter it by priority, routine, progress or equipment, switch between your Home and Gym equipment, shuffle it for variety, and step back through past days to log what you did. A 🔁 Routine button under the search box swaps the whole list for one routine, essentials first. Print a clean copy or export it as a spreadsheet.

⏳ The To-Do List

A ranked list of what to do next — just what's due, nothing else. Open a Target inline to check its Exercises without leaving the page, or narrow it by priority, Category and list size.

🎯 Goals that roll

Goals read as “3 times every 7 days”, and the window rolls — always the last 7 days counting back from today, never a calendar week that resets on Monday. Any length works the same way, 30 days or 365.

The one exception is the three built-in Weekly, Monthly and Yearly Goals Categories: those use real calendar periods, so a single check covers the whole week, month or year.

🟣 One color to learn

Magenta means a goal isn't met yet in its window — a rolling stretch that moves with you, not a deadline. Do those first; everything else can wait. It's the whole priority system in one cue.

🔥 Streaks & points

Each Category, Target and Exercise keeps its own streak: the days in a row you did it. Points are a score per activity, worked out from how hard it is and how much (about 5 for 30 minutes of moderate effort), shown on its page, totalled on the Dashboard and charted over time. Past about 2 hours of moderate effort, more counts for less. Negative points mark things you shouldn't be doing.

📈 History that means something

Every Category, Target and Exercise has its own page with completion history, per-day notes, and an amount you can log (reps, weight, minutes, miles). One box per set, up to five, so three sets in a day are recorded as three. Charts compare periods, narrow to one Category, and export to CSV.

🎥 “How do I actually do this?”

Every exercise carries its own written steps, the muscles it works and the equipment it needs — plus one-tap How To buttons that search YouTube, Google, ChatGPT or Gemini for that exact movement, so you're never guessing at form.

🎯 What you've been avoiding

Your Home page calls out the muscles you haven't checked off in a while, longest-neglected first, with the exercises that would fix each one a tap away. Checking the muscle clears it from the list, and so does checking one of its exercises, which checks the muscle for you.

📝 Days that look too quiet

qFIT also flags days in the last month with barely anything logged — because usually you did the thing and forgot to check it. Tap a day to open its checklist, or fix several at once in Catch Up.

🧭 A nudge while you're finding your feet

Home keeps a short Getting Started list of things worth setting up. Rows check themselves off as you actually do them, and you can check the rest by hand; either way they clear off the list, and Show Completed Items brings them back. It disappears once you've worked through it.

Setting It Up (Once)

qFIT is meant to fit you, so almost everything is adjustable — but you can skip all of it and start from templates. Nothing here is required to begin.

Starter templates

Apply a sensible starter set of Categories, Targets and Exercises in one tap, at the level of muscle detail you want. Includes a recommended set aimed at preventing common pains and muscle loss.

Add from the library

Search a large shared activity library and tap to add — exercises, stretches, machines, sports and everyday activities. Anything missing, you add yourself; your own entries are private to you.

🔁 Routines

Start one of the ready-made ones from Routines, or bundle the things you do together into your own — Morning, Bedtime, Gym Day, Pre-Bike Warm-up — and mark which rows are its essentials. Each one becomes a filter on your Checklist, so a whole session is one tap away, and yours stay private to you. Splits across several days are supported. Or customize a ready-made one: hide what you don't want and add anything else, just for you.

🏋️ Only what you can actually do

Tell qFIT which equipment you have — individually, or with Full Gym / Home Gym / Bodyweight presets — and exercises you can't do stop cluttering your list. Nothing is deleted; flip it back any time. Set it up twice, once for Home and once for the Gym: an Equipment dropdown on the Checklist, To-Do and Home picks which one is in use, and every list follows.

👁 Show, toggle or hide

Every item is Show (always listed), Toggle (listed unless you narrow the view to Show Only), or Hidden — kept on file with its history intact, and a double-click or press-and-hold on its row opens Quick Edit to bring it back. It's how you keep a big library without a long list.

⚡ Change a lot at once

Bulk-edit visibility, priority, points and goals across dozens of rows in a grid — each change saves itself, with no Save button to remember — set every goal at once from a preset, color-code your Categories, and drag them into the order you think in.

Tools

⏱️ Workout Timer

Interval, rest and stopwatch modes with one-tap Tabata / HIIT / EMOM / 40-20 presets, audio and vibration cues, and a screen that stays awake mid-set. Your settings are remembered on the device.

🧮 Fitness Calculators

Seven of them — BMI, body fat, daily calories, macros, one-rep max, running pace and water intake. Enter your stats once and they all recompute; the 1RM one builds a full percentage table. The math runs in your browser and nothing here touches your Checklist. Logged in, Your Stats follow you to your other devices; each calculator's own numbers stay on the device you typed them on.

❤️ Heart Rate Zones

Your personal BPM ranges from any of thirteen published zone models and nine max-heart-rate formulas, refined by your resting and threshold rates if you know them. Logged in, your settings are saved to your account.

🔥 Calories Burned

About how many calories popular activities burn — walking, running, biking, swimming, racquet and team sports, gym classes, even mowing the lawn — in a usual session and per hour, at your weight. Sort by most calories per hour (the default), per session or A to Z. Your weight is saved to your profile.

💪 Muscle Guide

What every major muscle does, where it is, and the moves that train it — searchable by name, alias or exercise, filterable by region, with the commonly-overlooked stabilizers called out and a short list of the muscles everyone should know but many people can't name. More Details on any card says where exactly the muscle is and what a weak or a tight one feels like, and Typical Muscle Sizes shows what each one typically weighs, for men and for women.

⚖️ Body Metrics

Log weight, waist and body-fat percentage against a date — all three optional, fill in whichever you track — and watch the trend line. Saving the same date twice updates that day rather than piling up rows. Pounds and inches, or metric if you pick it in Preferences; private to you; nothing here touches your Checklist.

🗓️ Catch Up

Forgot to check things off for a few days? One 30-day grid backfills them all at once. Every check saves instantly, and an Undo sits at the top for a few seconds in case you clear the wrong day.

Learn & Stay Motivated

🛡️ The Essentials

Log in for the short list of what health experts recommend for nearly every adult, the most important first: the 10 that matter most for your age and gender, then everything else by topic, each with one line on why and a link to the details. Or switch to a list of its own for strength, stretching and massage, with the muscles we recommend for each.

💡 Fitness Tips

Training smart without overtraining or injury, recovery, fueling, and weaving movement into a normal day — skimmable, searchable, and distilled into rules of thumb at the end.

🩹 Common Problems

509 common problems — lower back pain, knee pain, sore feet, a stiff neck, tension headaches, poor sleep, low energy, stress, smoking, loneliness — with what's going on, the strength, stretching, massage and everyday habits that genuinely help, and when to get it looked at instead of self-treating, plus 51 common conditions and features of the body that no routine changes, with what does, and 10 guides to prevention, preparation and safety. 506 of the problems name one of 150 ready-made Routines built for them (out of 234 in all), which you can pick straight from your Checklist — which is also where every card on the page links, so the routine list is one tap away. The problems come in three groups: Very Common, Common and Less Common. Narrow it by topic or by how common, search it in everyday words, + Add to My List on the ones you have, ☆ a routine to make it a favorite, and save every page to your phone for when there's no signal.

🩼 Injuries

61 common injuries, head to toe — ankle sprains, pulled hamstrings, tennis elbow, a torn ACL, a broken wrist, concussion — with what to do in the first few days, the rehab that helps, how long getting back usually takes, how to stop it happening again, and the ones to have checked first. Every one has a Recovery routine, and each links the routines that help (36 in all), labeled Recovery, Prevention or Also helps, with a ☆ to make one a favorite. Filter by where it hurts, what got hurt and how it happened.

🤒 Colds, Flu & Stomach Bugs

Two guides on one page: how to lower your odds of getting sick in the days before something you cannot miss, and what to do when a cold, the flu, COVID or a stomach bug has you. Every remedy and habit carries a label that says what studies found — shortens it, eases symptoms, standard advice, no benefit found — with its sources, the signs that need a doctor first, and a routine for each guide that opens in your Checklist.

🎂 Health at Your Age

Which of 62 screenings, shots, checkups and everyday habits are recommended at your age, from US guidelines with the date each was issued — plus which of 184 everyday problems become common around your age, the routines that help you get ahead of them, and the other 376, which are not tied to an age. Put one on your To-Do with its real schedule, even “every 10 years”, print your questions for the next checkup, keep the ones you care about on My List, and a card on Home tells you what's new at each milestone birthday.

🔥 Motivation

One honest account of why most “permanent” aches turned out to be fixable — and the patterns behind them, including why the pain is rarely where the problem is.

📅 How I Use qFIT

Worked examples of how qFIT fits into real days — mornings, gym days, at home, bedtime. These are somebody's example week, not a report of your data.

🎲 Try Something New & Recommended Activities

Hand-picked ideas that aren't on your Checklist yet, and the picks we'd suggest to almost anyone. One tap on + Add puts either kind on your Checklist.

📖 Glossary, Tutorials & Tips

Every fitness and qFIT term in one searchable place, a short guided tutorial on most screens, and the shortcuts that make daily tracking faster.

🧭 Quick Tour & Full Manual

The friendly version first — the three levels, your weekly Checklist, how to read the counts, and the Dashboard — then the full manual when you want every option explained.

🧰 Troubleshooting & Site Map

What to try when something won't save or a page looks stuck — ordered least disruptive first, so step 1 costs you nothing — and a searchable index of every page you can open, grouped the way the menus are.

❓ The Help page

One page that gathers all of the above — full manual, quick tour, tutorials, tips, glossary and troubleshooting — so you never have to remember which one had the answer.

Who It's For

Fitness apps are often built for bodybuilders and fitness nuts. qFIT works for them too — but it's especially useful for the rest of us:

  • Average people who want to get fit and stay fit — especially if you don't know where to start.
  • Anyone who just wants to do the bare minimum to avoid aches, pains, and age-related issues.
  • Anyone who tends to be inactive, unmotivated, or simply busy.
  • Anyone who sits for a large part of the day.
  • Anyone trying to stay on track with physical therapy.
  • Anyone wanting to prevent or delay stiffness, poor range of motion, or muscle loss.
  • Athletes and bodybuilders who want a simple, actionable plan to keep them on track.
  • Anyone who wants to work exactly the right muscles without hours of research.

What Makes qFIT Different

It's free, and it's built to be simple, customizable and actually doable — because the program you keep doing beats the program you quit, and that's THE most important thing. It's designed for every day, not just gym days: most of what's on your list takes a minute, so there's always something you can check. Start from templates, then dial it up or down: add any sports, activities, workouts, and exercises you like, set a few goals, and get at it. There's always something new.

Free

100% free. No ads, no upsells, no “premium” wall. Every feature is available to everyone.

Private

No third-party ads or trackers, and we never sell your data. Anything you create is private to you. See Security & Privacy.

Doable

One job done well — tell you what to do next so you actually keep going, week after week.

The Words You'll See in qFIT

qFIT organizes everything into three simple levels:

1. Category

The top level — a broad area like Stretching & Mobility, Strength & Workouts, or Nutrition.

2. Target

A focus inside a Category — usually a muscle or goal, like Quads or Core.

3. Exercise

The specific thing you do — an exercise, stretch, machine, sport, or activity. This is what you check off.

✅ Checklist

Your main qFIT list — everything you can do, with checkboxes. Check things off as you go.

⏳ To-Do List

A short, dynamic list of what to do next, based on your goals and priorities.

🔁 Routine

A saved bundle of things you do together (Morning, Bedtime, Gym…). Browse and start one on the Routines page, or with the 🔁 Routine button on the Checklist.

🎯 Goal

How often you intend to do something — “3 times every 7 days”. The window rolls; goals drive what qFIT suggests.

A Few More qFIT Words

Magenta Tag

You haven’t hit this goal yet in its window — a reminder, not a deadline. It clears the moment you reach the target.

Streak

Days in a row you did one particular Category, Target or Exercise — each keeps its own. It counts completions, not whether you hit the goal, and stays alive if the last one was today or yesterday.

Points

An optional per-activity score reflecting effort and long-term benefit. Totalled on the Dashboard and chartable alongside plain checkbox counts.

Visibility

Whether an item always Shows, is a Toggle that drops out only when you narrow the view to Show Only, or stays Hidden — kept on file, with its history, but off your list.

Priority · Enjoyable · Effective

Priority ranks your To-Do list and can carry its own, more frequent goals. Enjoyable and Effective are your own ratings, which the Checklist can filter on.

Split (1/3, 2/3, 3/3)

Routines that divide a workout across several days — common for gym programs.

Essentials · Full

A routine opens on its essentials — the rows it marks as mattering most — and Full shows every row in it. Anything you've already checked stays on screen either way.

Recommended for my problems

One combined routine made from every routine matched to what you picked under My Problems, Injuries & Interests on your profile. Pick none and it doesn't appear.

Site Mode

How much of the interface is shown — Simple, Standard (where new accounts start), or Everything. On qFIT today it only hides the two extra filters on your To-Do list; more is planned.

Muscle Detail Level

How finely your muscle Targets split the body — High-Level, More Detailed or Most Detailed, chosen separately for Strength, Stretching and Massage on Quick Checklist Setup. A muscle follows its level unless you set that one muscle by hand. Different thing from Site Mode.

📖 Every one of these — plus more than 130 fitness, training, anatomy, cardio, strength, nutrition and recovery terms in plain English — is on the Glossary page, with a search box. You don't need to know any of it to start.

Make It Yours

As much app as you want

Simple trims the interface, Standard — where new accounts start — is the everyday default, and Everything is for tinkerers. Switch any time in Preferences. On qFIT it currently changes just one thing: Simple hides the two extra filters on your To-Do list. Nothing is ever switched off, and no page is closed to you in any mode.

Looks the way you like

Dark mode, text size, page background, per-Category colors, and one answer to “where should qFIT open?” that the logo, logging in and the installed app all follow — including where I left off. Everything previews as you pick it and follows you to every device you're logged in on.

Reminders, not nagging

Opt into a daily nudge, a start-of-week one, or neither — by push, by email, or both. Turn them on in Preferences; subscribe a device and set Quiet Hours on Notifications. Email can go to a different address from the one you log in with, and Quiet Hours silences push (uncheck Email if you want silence there too).

Works at the gym

Install qFIT to your home screen and it launches full-screen, and To-Do, How I Use qFIT, the Dashboard and Home still open to read with no signal — useful in a basement studio or a dead-zone gym. The Checklist opens too if you pressed Save This List for Offline on it first; what you check off or log there is sent when you're back. Catch Up needs a connection. No app store, nothing to download.

Nothing to configure

Your time zone is detected from your device, so the day rolls over at your midnight and follows you when you travel. Sessions last a year, so you stay logged in.

Your account, your call

Log in with Google or a username and password, and change either any time. A login from a device none of our sites has seen before can ask for a six-digit login code emailed to you — switch Two-Step Verification on in Account & Security (it starts off), and you can forget your other trusted devices in one tap. Left yourself logged in somewhere? Log Out Everywhere ends every session at once. Export your history whenever you like, and if you want to stop, deactivating hides your account without erasing anything (ask us and we'll switch it back on).

Free, No Ads, No Data Sharing

qFIT is 100% free. No ads, no upsells, no “premium” wall, no trackers, and no credit card. Every feature is available to everyone — there is no paid tier holding anything back. We never sell your information, and your training data is yours.

We're just trying to help others and share what we've learned. Have an idea or hit a bug? Tell us — every submission gets read by a human. Your My Messages keeps what you sent and anything we wrote back, and what shipped is listed on What's New.

📋 Detailed List of Features

Everything qFIT does, in one place. You don't need to read this to get started — the setup wizard walks you through it. This is here for people who want to know exactly what they're joining.

The Daily Loop

  • Check a box to log an activity. Check it again to undo it. That's the whole interaction.
  • Your Checklist is a tree with three levels — Category, Target, Exercise — so you can log “Stretching” as one check, or the specific stretch you did.
  • Step back and forward a day at a time, or jump straight back to today, to log against a different date.
  • Choose which day a check is recorded against, so a late-night session lands where you want it.
  • Log a set at a time — one box per set, up to five, for the day you're on.
  • Write a note against the specific day you checked something off: what weight, how it felt, what hurt.
  • Catch Up backfills days you missed, with its own filter, then drops you back on today.
  • A To-Do badge in the nav shows how much is due right now, from any page.

Getting the List Down to What You Can Face Today

  • Filter the Checklist by priority, Category, routine, visibility, how effective it is and how much you enjoy it — plus a Randomize option when you want the decision made for you.
  • A row of chips names every filter narrowing your list — × on a chip drops that one, Clear Filters drops them all, and 🎲 Re-Randomize reshuffles the random pick.
  • A 🔁 Routine button under the search box shows which routine is on and switches it, next to a link to every routine. With one on, Essentials shows just the rows that matter most — plus anything you've already checked, with a dotted border on any row that is only there to show where an essential sits — and Full (or Show All at the bottom) shows the whole routine.
  • One Equipment dropdown switches the list between your Gym and Home equipment — the same choice To-Do and Home use, so changing it in one place changes it everywhere.
  • Machines Only, in the same dropdown, keeps just what you can do on a gym machine, and any single type of equipment below it does the same for that one thing. The dropdown is shared by the Checklist, To-Do and Home's neglected-muscles card.
  • Home and Gym presets: set your filters and options the way you like them in each place and save them, then pick GYM PRESET or HOME PRESET in the Equipment dropdown to switch between the two.
  • Search the tree, choosing how wide the search reaches.
  • Show or hide columns: progress against goal, when you last did it, the priority pill, points, and the running total.

Every Activity Has Its Own Page

  • Stat boxes with the headline numbers for that exercise at a glance.
  • A completion history showing every day it was logged, and how many times.
  • Your current streak, with the streak rules written down so you know what breaks one.
  • A hold timer built into the exercise itself, for stretches and holds you're meant to time.
  • A day stepper, so you can move backwards and forwards while logging.

The To-Do List

  • Just what's due now, ranked by what it needs — a muscle you trained yesterday is set apart under 🛌 Resting Today rather than pushed at you again. Nothing else.
  • Open any row and log completions against it without leaving the list.
  • Filter by what to show, priority and Category, and cap how many appear.
  • Measure the list against your own goals, or against our recommended goals for the intensity you've chosen — and with All Categories picked, both at once: our goals for your muscles, plus your own goals for everything else.
  • A screening you added from Health at Your Age shows on the list when it's due, marked 🩺 SCREENING — even when you're measuring against our recommended goals.
  • Sort the rows most urgent first, largest muscles first, or A–Z.
  • Choose how finely muscles are broken out, so the list matches how you think.
  • An explainer shows exactly how the list decides what comes first. It isn't a black box.

Your Home Page

  • Quick actions — one tap to the things you do most.
  • Reminders, and a “did you log everything?” prompt so nothing quietly slips.
  • Neglected muscles — what you haven't worked recently, with control over what counts as neglected. When your strength check-offs lean too far toward some muscle groups, a Strength balance line on the same card says what to do less of and what to focus on.
  • Getting Started: a short list of sensible next actions, which you can reset or hide once done.
  • A 🔁 Try a Routine card with up to three routines to start in one tap — your starred favorites if you have any, otherwise the ones recommended for your problems, otherwise a trio of the most common that changes day to day — until you hide it.
  • A 🎂 birthday card on a birthday that brings something new — a screening or shot that starts at that age, or everyday problems that become common around it — once your profile has your birthday. Hide it and it stays hidden until the next one.
  • Collapse any card you don't want, and it stays collapsed next time.

Seeing That It's Working

  • Dashboard: how many of your goals you're meeting, each over its own rolling window; your momentum; streaks and records for your exercises; and what's still outstanding by type and priority. Numbers only; what to do next is on Home.
  • Strength Balance, on the Dashboard: what share of your strength check-offs went to each of seven major muscle groups, beside a target share for each, with a plain-words summary of what is high, what is low and what you might trade for what. It looks at the mix, not at how long it has been, over the last month or a longer period you pick (3, 6 or 12 months), and its last line also shows on Home.
  • Charts: activity over time by week, month and longer ranges, switchable between counting check-offs and counting points, with a breakdown by Category, Target and Exercise.
  • Save any chart as an image, or download the day-by-day numbers behind it.
  • Body Metrics: log weight, waist and body fat over time and see the trend. One entry per day; saving again replaces that day.

Goals

  • Set how often you want to do each thing, at all three levels, plus muscle and non-muscle groups.
  • A goal on a Category, Target or Exercise can stretch to once every 2, 3, 5 or 10 years, for things like a colonoscopy or a tetanus booster.
  • Start from your Fitness Goal / Intensity (Bare Minimum, Moderate, Aggressive or Extreme) instead of filling in dozens of numbers.
  • Give every muscle its own recommended goal for that level, or one goal of your own for every muscle.
  • Set different, harder goals for the rows you marked high priority.
  • See exactly what's about to change, and confirm, before goals you already set get rewritten — and undo a bulk save you didn't mean.
  • Save one section at a time, or all at once.

The Four-Step Setup, Done Once

  • Quick Start — what qFIT is and how the Checklist works, before the four steps.
  • Quick Checklist Setup — starter templates fill your Checklist, at a level of detail you set separately for Strength, Stretching, Massage and everything else. The three muscle levels are your Muscle Detail Levels: they decide which muscles are on your list, and this is the one place to change them.
  • Quick Add — switch on what you already do. Toggles save instantly; there's no Save button to forget.
  • Edit Filters — tell qFIT what equipment you have and it hides what you can't do, with one-tap presets. Home and Gym keep separate equipment, and an Equipment dropdown on the Checklist, To-Do, Home and the Dashboard randomizer switches between them. A second card hides everything that works an area you're injured in or can't work, and stops scoring you against it.
  • Edit Colors — give every Category its own color, from Blues, Greens, Grays, Rainbow or striped, with a live preview before anything saves.

Building Your Own Library

  • Add or edit an exercise with the muscles it works, how to do it, alternate names, equipment, your notes and the units you measure it in.
  • Add or edit Categories and Targets with colors, goals, scheduling, visibility, priority and points.
  • Rate an exercise for how effective and how enjoyable it is — then filter your Checklist on exactly that.
  • Mark a Target as a muscle so it counts toward muscle goals and the neglected-muscle card.
  • Mark a Target as a penalty — something you're trying not to do. The checkbox changes meaning, and checking it can take points off the day.
  • Decide per Category whether it shows a checkbox of its own, whether it shows the date you last did it, and what it's worth in points — and check a Category off for a day directly on its own page.
  • Choose whether a Target appears in the weekly summary at all.
  • Routines: a saved set of Targets and Exercises you do together, like Gym Day. Build your own on Edit Routines, mark which rows are its essentials, and only you can see it. Or make a ready-made one your own there: hide what you don't want and add anything else, and it reads “(custom)” in your lists while everyone else keeps the original.
  • The Routines page — a card for every ready-made routine and each of your own, saying what it's for and how many rows it holds. Search it in any word order, narrow it to the most common, the ones built for a problem, the ones recommended for you, your favorites or your own, and ▶ Start one. Logged in, each card also names the problems it helps with, and a ☆ stars it so it leads your Checklist's Routine list and Home's Try a Routine card.
  • Common Problems — 509 common problems, from aches and stiffness to poor sleep, stress, smoking and loneliness: what is actually going on with each, the strength, stretching, massage and habit work that helps, and the ones to have looked at before self-treating. 506 name one of the 150 ready-made routines built for them — out of 234 routines in all — that you can put straight on your Checklist.
  • A Guides section holds 10 guides to prevention, preparation and safety — getting fit before an operation, getting ready for a birth or a ski season, ACL injury prevention, neck strength for contact sport, keeping up with checkups and screenings, massage tool safety, doing too much too soon and the warning signs that need a clinician — each with its own page and routine. They are not counted as problems and are not part of My Problems; a Guides dropdown includes them, shows only them, or leaves them out.
  • A last section covers 51 common conditions and ordinary features of the body that no exercise or habit routine changes — appendicitis, hair loss, needing reading glasses, cellulite, eye floaters — each with what does treat it, or that nothing reliably does, what you can do yourself, when to get help, and links to the related problems a routine can help with.
  • Find a problem by body part or area of life, by how much exercise can do for it (the main treatment, a strong help, relief and prevention, or see someone before self-treating), by what helps (strength, stretching, massage, balance, breathing), with injuries shown, on their own or left out, the same for the conditions with no routine, or by searching in everyday words — plurals, “sore”, “hurts” — and the list keeps your filters when you come back from a problem's page.
  • Each problem has a page of its own, and more than 230 of them go deeper: by the numbers, the types and patterns, how it's assessed, a typical timeline, myths and facts, common questions, questions worth asking a clinician, and the research behind the page, linked.
  • With a gender on your profile, the list leaves out the problems only the other gender's body has — the Men's and women's problems dropdown brings them back, and anything you've selected always stays.
  • A folded card, Problems Made Worse by Smoking, Alcohol or Cannabis, lists for each habit the problems whose own page names it as a cause or as something that makes them worse — tap a name to open that problem. The three habit pages (Smoking and vaping, Drinking too much, Using too much cannabis) each carry the same list for their habit, and every link on it is backed on the problem's own page by a named study or health-body statement. Links that are plausible but not proven — the evidence is thin, mixed or from a single study, or is about something close to the problem — are kept apart in a dashed Less Certain box under each list, and on the problem's own page that sentence starts with “Less certain:” and says what limits it.
  • + Add to My List on the problems you have, on any card or problem page — the same private list as My Problems, Injuries & Interests on your profile, where you can also pick things you'd like to prevent or just learn about — and a My List pill shows just those.
  • Tap the ☆ after any card's routine to make it a favorite — the same star as on the Routines page.
  • Save All Guides for Offline puts every problem page — and every other guide — on your phone to read with no signal, and takes them off again when you're done.
  • Recommended for my problems merges every routine matched to what you picked into one list — on the Checklist, at the top of the Routines page and on Home. Your picks are optional and private: no one at qFIT looks at them, they're never shown or shared, and they're used only to suggest routines to you.
  • Injuries — 61 common injuries, head to toe, from ankle sprains and pulled hamstrings to a torn ACL, a broken wrist and concussion: what happens, what to do in the first few days, the rehab that helps, getting back to it, preventing it, and the ones to have checked first. Every one has a Recovery routine, and each links the routines that help — 36 of them — labeled Recovery, Prevention or Also helps, with the same ☆ favorites and + Add to My List button as Common Problems.
  • Colds, Flu & Stomach Bugs — one guide for the days before a big event and the first signs of a cold, and one for when you are sick: each remedy labeled with what studies found (Shortens It, Eases Symptoms, Lowers Your Odds, Protects Others, Standard Advice, Evidence Unclear, No Benefit Found, Can Backfire), every source listed, when to call a doctor or 911, and two ready-made routines, Don’t Get Sick and Sick Day.
  • Drag Categories into your own order, or sort A–Z. Every move saves itself.
  • Bulk Edit: change visibility, priority, points or goals across dozens of rows at once, every change saving itself.
  • Hide instead of delete — hiding keeps the history, deleting erases it, and the difference is spelled out where you choose.

Learning Your Way Around Your Own Body

  • A muscle guide — 117 muscles across six regions, each saying in plain words where it is, what it actually does and what trains it, with 27 flagged as the ones almost nobody works, 26 marked as recommended and 20 as having no gym machine. Search it by the problem rather than the name, so “shin splints” and “plantar fascia” land on the muscle behind them. Every card opens to More Details: where exactly the muscle is, what a weak or a tight one feels like and, where it matters, when to get it checked. A Typical Muscle Sizes card ranks the muscles by what they typically weigh, for men and for women, from published measurements.
  • An organ guide — 40 organs across eight body systems: what each one is, what it does, and the everyday habits that keep it working. Every card ends with real Targets and routines you can open straight from it, so “look after your liver” turns into something you can actually check off.
  • Health at your age — which of 62 screenings, shots, checkups and everyday habits US guidelines recommend at your age, each with how often, what it's for, what to ask your doctor, its source and the date its guideline was issued, and every “ask your doctor” line gathered into one printable list for your next checkup; which of 184 everyday problems become common around your age, with the routines worth starting before they do; what's coming in the next five years; the other 376 common problems, which are not tied to an age, grouped by how common they are; and recommendations whose age range ended recently. Conditions like smoking appear as “If…” lines to read — it never asks. Put one on your To-Do with its real schedule, from every day to every 10 years, and log the date you last had it so it isn't counted as overdue; one-time tests and finished vaccine series show as done. Tap + Add to My List on anything you want to keep an eye on and the My List view shows only those — with the ones that belong to another age listed at the bottom, so none goes missing — and your watch list follows you to your other devices. A ☆ beside any routine it suggests makes that routine a favorite, the same as on the Routines page. It opens at the age and gender on your profile, shows items for women and men alike when your profile doesn't say which, and lets you look at any other age without saving anything.

Tools You Can Use Without Joining

  • Seven fitness calculators sharing one Your Stats card, recalculating as you type: BMI, body fat by the tape method, daily calories (BMR and TDEE), macros, one-rep max, running pace and water intake. Imperial or metric with one toggle.
  • A workout timer — interval timer, rest timer and stopwatch in one page, with one-tap Tabata 20/10 ×8, HIIT 30/30 ×10, EMOM 60s ×10 and 40/20 ×6, audio and optional vibration cues. Keeps running with no signal once it's open, and holds the screen awake so your phone doesn't sleep mid-set.
  • Fitness tips — training advice rather than app help: training safely, recovery, fuel and everyday fitness.
  • Heart rate zones from your age and resting rate, using any of thirteen published zone models — Karvonen, %HRmax, the AHA moderate/vigorous split, all three Garmin methods, Apple Watch's automatic zones, Friel for running and cycling, Coggan, Seiler's polarized three-zone, Zoladz and Maffetone MAF — and any of nine age-to-max-heart-rate equations, with the sources cited. (Needs an account, so it can save them.)

Staying Interested

  • Try Something New — a hand-picked gallery of ideas that aren't on your Checklist yet, where one tap adds one.
  • The activity randomizer shuffles you something to do next, with control over what it draws from.
  • Recommended activities, plus an Also Worth Doing card on Home for upkeep that isn't an activity — a weigh-in, or the days you forgot to log or only partly logged.
  • How I Use qFIT — worked examples of fitting qFIT into a real day.
  • Motivation — why most aches and pains aren't “getting old”, and what actually fixed them.

Getting It Out of the App

  • Print a clean copy of the Checklist, or save it as a PDF.
  • Export the Checklist to a spreadsheet — choose the date, the number of rows and the layout, with a preview and copy-to-clipboard.
  • Export your whole check-off history for any date range.
  • Export the To-Do list, the chart data, or the numbers behind a chart.

Reminders That Respect You

  • Push on the devices you choose, email to an address you choose, or both — and the page tells you which address reminders are actually going to.
  • Quiet hours, and a Do Not Disturb that silences push for 12 hours — email reminders still arrive.
  • Turn push off on just the device in your hand, without touching the others.

  • Your profile: name, contact details, a backup email and phone, location, time zone, birthday and gender — the last two are what Health at Your Age opens with.
  • US or metric units for Body Metrics, chosen once in Preferences.
  • Themes including dark mode, font size, a re-tintable background, site mode, and which page qFIT opens on. The color editor previews every change live and saves nothing until you press Apply, with ↺ Reset and a ↺ Shuffle if you would rather it picked.
  • Bring back every dismissed inline tip or the Welcome card, whenever you want them again.

Help, If You Want It

  • A quick tour of the three levels, the weekly Checklist, reading the counts and the Dashboard.
  • A short tutorial on most pages, behind the ❓ button and replayable any time.
  • Dismissible inline tips, with one reset that brings them all back.
  • A searchable glossary — and the search reaches the definitions, not just the titles.
  • A tips page with a Recommended For You section based on how you actually use qFIT.
  • A site map you search by what you want to do rather than by page name, and, for trusted members, an All Pages list color-coded by who can open each one.
  • A Help hub that gathers the full manual, tutorials, tips, glossary and troubleshooting in one place.
  • Troubleshooting for when something is stuck, including a Clear Cookies button that tells you what it keeps, a way to clear the cached copy this device is holding, and what to try when it's your Internet connection rather than qFIT.
  • What's New — the release notes, filterable and paged, with a badge in the navigation when there's something you haven't read.
  • Press ? on any page for keyboard shortcuts.

Getting Hold of Us

  • Contact us with a problem, an idea, a question or anything else — the form changes what it asks depending on which you pick, and takes screenshots and file attachments.
  • Everything you send is kept in your own message log, with any reply, searchable and filterable and paged.
  • A feedback button on every page that already knows which page you're on.
  • Donate if you want to, by PayPal or Venmo, with suggested amounts or your own — or copy the link instead of opening it. Nothing in qFIT is locked behind it.

Bringing Somebody With You

  • Invite by email with one-tap common domains, hand your join link to any app, copy it, or let someone scan a QR code.
  • A Contact List: find someone already on qFIT by their exact email address or phone number, add them without them being told, see who hasn't added you back yet, and block anyone you'd rather not see — the same list qMEET and PacklistPRO use.
  • Compete with your mutual contacts over the last 30 days — on variety as much as volume, with an all-time board of everything you've tried — and choose whether your own counts are shown to your contacts or to nobody.
  • The page tells you plainly what actually credits an invite to you.

Trust and Account Safety

  • Two-step verification is one check away in Account & Security.
  • Log in with Google if you'd rather not have another password.
  • Log out everywhere ends your session on every device, this one included, and Forget My Trusted Devices makes every other device ask for a login code again.
  • Deactivate your own account yourself, without emailing anybody.
  • The Join form explains itself — every field has a “why do you ask?” explainer.
  • See recent activity on your own account, so you'd notice something you didn't do.
  • Password recovery answers the same either way, so it never reveals whether an account exists, and the account locks after repeated wrong passwords.

One Account, Three Sites

  • Your qFIT login is the same login for qMEET (local events, groups and people who share your interests) and PacklistPRO (trip packing and planning). One account, one password, nothing to join twice.

It Works Where You Are

  • Works offline — a banner appears and pages you've already visited still load; a check-off or a logged day made offline is kept on the phone and sent when you're back; any other change needs a connection, and the page tells you so.
  • Whenever qFIT has to show you a saved copy of a page, a bar across the top says so, says when the copy is from, and offers Reload — so a weak signal never passes old numbers off as current.
  • If a page can't load at all, the offline page lists everything saved on the device — routine lists, exercises, problem pages, guides and other pages you've visited — one tap each, and it tells apart being offline, not reaching qFIT, and qFIT itself having trouble.
  • Save every Common Problems page to the device in one tap before you lose signal.
  • Save This List for Offline on the Checklist and To-Do keeps the list — the routine you're about to do, or your whole checklist — on the device, with the details page of everything on it, and brings it up to date each time you open the list with a connection.
  • Save All Guides for Offline, the same button on every guide page, downloads all the guides in one press: The Essentials, the Muscle Guide, Organ Guide, Common Problems and every problem page, Injuries, Health at Your Age, Colds, Flu & Stomach Bugs, Fitness Tips, Glossary and Tips.
  • Install it to your home screen like an app, with separate iPhone/iPad and Android instructions.
  • Three site modes — Simple, Standard and Everything — today Simple only hides one To-Do filter, Maximum to Show.
  • Themes including dark mode, adjustable text size, a re-tintable background, and a choice of which page qFIT opens on.
  • iPhone HEIC photos are converted in your browser before upload, so they attach like any other picture.
  • A feedback button on every page, with screenshots, about that exact page.
  • If your session expires you're offered a way to stay logged in, instead of silently losing what you were doing.
