TRAIN WITHOUT WATCHING YOUR PHONE
With an active workout session, the countdown and audio continue while your iPhone is locked or in the background. Compatible music apps keep playing at a lower volume during cues. iPhone haptics work in the foreground; Apple Watch provides wrist cues during its workout.
APPLE WATCH, HEALTH AND HISTORY
Run workouts on Apple Watch and sync programs with your iPhone. With your permission, save workouts to Apple Health and display heart rate from Apple Watch or supported AirPods Pro 3. Review workout history, streaks, badges and trends, or export your history as CSV.
MAKE IT YOUR WORKOUT
Create programs with your own exercise names and reference photos. Share programs by link and preview imported workouts. Add the Control Center widget to open the app with your last-used settings.
ON-DEVICE COACH AND PRIVACY
Coach builds workouts on device. On supported devices, Apple Intelligence can help choose the coaching explanation; workout generation still works when Apple Intelligence is unavailable. No workout or health content is sent to a third-party AI service.
Firebase Analytics is optional and stays off until enabled in Settings. It uses pseudonymous identifiers; our Analytics events exclude workout and health data. This version removes Firebase Crashlytics. No advertising ID.
