Just'a Tabata: A Workout Timer

Set your rounds, hit start, put the phone down. Beeps and a live Lock Screen timer keep you on pace — on iPhone, iPad and Apple Watch, together.

An interval timer that gets out of the way.

Build a workout in seconds — work, rest, rounds, sets — then start it and put the phone down. Just'a Tabata calls the changes with clear beep cues, keeps running while you're away from the app, and shows a live countdown on the Lock Screen and in the Dynamic Island.

One person, one workout, two screens. Start, pause, skip and end together on iPhone and Apple Watch when both are open — or run them independently, for two people training at once.

• Work / rest / rounds / sets, exactly as you want them • Beep cues, voice countdown and exercise announcements • Live Activity on the Lock Screen and Dynamic Island • Apple Watch app with the same controls • Home Screen widgets • Progress history, kept on your device

No account. No cloud. Nothing you record leaves your phone.
