Interval Timer · HIIT & Yoga

Build any interval workout in a minute. Then put your phone down and train — the timer handles the countdowns, the cues, the music, and your history.

Boxing rounds, HIIT, Tabata, yoga flows, kettlebell circuits, mobility sessions — one timer runs them all, on iPhone, Apple Watch, Apple TV, and any AirPlay-compatible screen. Live heart rate on the iPhone and on the TV when you cast.

One-time purchase. No subscription. No ads. No tracking. $4.99 at launch, $7.99 regular price. Pay once and the app is yours — every feature, every device, forever.

Built for everyone who's tired of timers that pause your music between intervals, lock saved routines behind a paywall, or interrupt your workout with full-screen ads you can't close.
