Stopwatch
Counts up from zero. Tap Start to run, Reset to clear.
Quick Guide
- Tabata — 20s all-out work, 10s rest, 8 rounds (4 minutes).
- HIIT — alternating hard/easy intervals; try 30s on / 30s off.
- EMOM — "every minute on the minute": do the reps, rest what's left of the minute. Set Work = 60, Rest = 0.
- Sets repeat the whole round block, with an optional longer rest between them.
⏱ Keep It On Screen
The Interval and Rest countdowns only advance while this page is visible. Switch tabs or apps, or let the phone lock, and they stop.
Come back and the page tells you how long it was paused and waits for you to tap Resume — the countdown carries on from the exact second it stopped, so nothing is skipped. Beeps and vibration don't fire while you're away either.
The Stopwatch is the exception: it's read off the clock, so it keeps counting while you're away — only its display stops updating, and it catches up when you return.
While running it asks to keep the screen awake, so on browsers that support it the display shouldn't sleep on its own.
💾 Nothing Here Is Recorded
No workout is saved. Running a timer doesn't tick anything on your Checklist and never appears in Charts.
Your settings do save, and follow you to your other devices once you login.
Editing Work / Rest / Rounds mid-run won't change the workout in progress — the edit applies on the next Start or Reset.
Turn Sound on before you tap Start. Audio unlocks on that first tap, so switching it on mid-run stays silent until you pause and start again.
