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. PURCHASE INFORMATION Yearly Pro renews automatically unless canceled at least 24 hours before the current period ends. Manage or cancel in your App Store subscription settings. Lifetime Pro is a one-time purchase. Your local price is shown in the app before purchase. Restore Purchases is available in the Pro screen.

What’s new
Version 1.2.4 · Updated October 19, 2026
Fixed voice prompts and beeps staying silent on a locked iPhone after an interruption such as a phone call. If workout audio is interrupted or refused mid-workout, the app now automatically reclaims it at the next cue. This fix addresses an issue reported by our users. Thank you for the feedback.
