Tabataly is a free interval timer for Tabata and HIIT workouts. No Ads, no in-app-purchases. No private data tracking. Set your activity time, rest time, and number of rounds. Every workout opens with a warm-up countdown, then repeats activity and rest for the rounds you chose, ringing a bell at every transition. The whole point: the bell rings even while the app is in the background — screen locked, another app playing audio, or the silent switch on — so you can train without staring at your phone. Tabataly runs entirely on your iPhone — no Apple Watch required. If you have one, the optional Watch companion adds haptic taps at every transition and can show your live heart rate and calories on your wrist; when you end the workout, it's saved to Apple Health with your permission so it counts toward your Activity rings. Your health data stays on your devices and in Apple Health — it's never sent to us or anyone else. • Simple setup: activity, rest, rounds • Warm-up countdown before every workout • A clear bell at every interval transition • Keeps ringing in the background, over other audio, and while muted • Works standalone on iPhone — no Apple Watch needed • Optional Apple Watch companion: wrist haptics, live heart rate & calories, and the workout saved to Apple Health
