Built for the workout, not the screen
Everything a Tabata or HIIT timer needs — and the one thing most of them get wrong.
The bell rings anywhere
Screen locked, another app playing audio, or the silent switch on — Tabataly keeps ringing a clear bell at every transition, over everything else, at full volume.
Dead-simple setup
Pick your activity time, rest time, and number of rounds. Start. That's the whole app.
Warm-up countdown
Every workout opens with a warm-up countdown, so you're ready before the first round.
Clear bell every interval
A distinct chime marks each activity → rest transition, so you always know where you are without looking.
Apple Watch companion
Run the timer from your wrist with haptic taps at every transition — glance down for reps and time, and leave the phone in your bag.
Counts toward your rings
With an Apple Watch, Tabataly shows your live heart rate and calories, then saves the session to Apple Health so it closes your Activity rings. Optional — the timer works great on iPhone alone.
How it works
Three numbers and a start button.
Set it
Choose your activity seconds, rest seconds, and how many rounds you want.
Warm up
Tap start and a warm-up countdown gives you time to get into position.
Go by the bell
Activity and rest repeat for your chosen rounds, with a bell at every switch — even in your pocket.
