Everything you need to know about Workout Timer.
No. Workout Timer is a single, one-time purchase. There are no recurring subscriptions, no hidden fees, and absolutely no ads. Buy it once, and own all studio voice coaches forever.
The app includes a dedicated standalone Apple Watch app that delivers tactile haptic taps on your wrist. When paired with iPhone, it streams live heart rate and active calories to your circular timer ring and Dynamic Island.
Yes! The app features intelligent Audio Ducking: whenever your coach announces a countdown or interval transition, it automatically lowers background Spotify or Apple Music volume, then immediately restores it.
It is an official 12-round core curriculum (30s Work / 20s Rest). During Work, it displays standard looping video form; during Rest, it automatically previews the upcoming exercise with an UP NEXT badge so you can transition seamlessly.
