Quick Start & Clean UI

A flexible, distraction-free interval timer. Start a Quick Start workout from your iPhone home screen in two taps.

Apple Watch App

Your workout on your wrist.

TimerCoach syncs live with your Apple Watch. See exactly what phase you're in, feel every interval transition as a haptic tap, and control the workout without touching your phone.

See the exercise, countdown, round, and next interval. When Apple Training is set for a workout, heart rate and active calories appear on Watch and iPhone.

Wrist Remote Control

Pause, skip to the next interval, or stop the workout entirely directly from your Apple Watch.

Haptic Phase Alerts

Feel every phase change through distinct Taptic Engine pulses — no need to watch the screen mid-set.
