Tabata & HIIT interval timer

Train to the bell.
Never watch the clock.

The bell keeps ringing even when your phone is locked, muted, or in another app — so you can move, not stare at a screen.

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.

10-second warm-up

Every workout opens with a fixed 10-second 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 — leave the phone in your bag.

How it works

Three numbers and a start button.

1

Set it

Choose your activity seconds, rest seconds, and how many rounds you want.

2

Warm up

Tap start and a 10-second warm-up gives you time to get into position.

3

Go by the bell

Activity and rest repeat for your chosen rounds, with a bell at every switch — even in your pocket.

Ready to sweat?

Tabataly is free on the App Store. No account, no clutter — just a timer that rings when it should.
