Workout Tracking From Your Apple Watch, Without Your Phone
RepXP lets you browse routines, start a session, log sets, edit weight and reps, track cardio, use rest timers, and finish your workout from your wrist.
What you can do from Apple Watch
The RepXP Apple Watch app is designed for the part of training where you want as little phone interaction as possible. Your saved workouts are available on your wrist, and the active session keeps the next exercise, planned sets, and rest time close at hand.
- Start and finish workouts: browse saved workouts and complete the entire session on Apple Watch.
- Log strength sets: confirm completed sets, change the reps or weight of the set you are about to do, and apply that change to the sets that follow.
- Track cardio: record duration, calories, distance, live heart rate, and time in heart rate zones for cardio sessions.
- Manage the session: move forward and back through the routine, skip an exercise, and get haptic rest timer alerts.
- See PR opportunities: RepXP can show when a planned set may break a personal record.
Start on one device and finish on the other
Two-way handoff means the workout is not locked to the device where it started. Begin on iPhone while reviewing your targets, then continue from Apple Watch after putting the phone away. You can also start from the Watch and move to iPhone later.
Review or start the workout
Open a saved routine on iPhone or Apple Watch and begin the active session.
Log from the most convenient screen
Confirm sets from your wrist or use iPhone when you want more room to review and edit.
Finish and review
Complete the workout on either device. RepXP processes workout history, XP, personal records, and reports on iPhone.
Apple Watch heart rate and cardio zones
RepXP can display live heart rate during a workout. When the session includes cardio, it can also show five heart rate zones and save a time-in-zone summary with the completed workout.
The zones follow the heart rate reserve method that Apple's Workout app uses, with each boundary set from your resting and maximum heart rate. The Apple Watch supplies the heart rate readings while you train. RepXP asks for Apple Health permission to read them, and the rest of the app keeps working if you decline.
Compatibility: RepXP requires iOS 18.0 or later. The Apple Watch app requires watchOS 11.0 or later. RepXP is currently available in English.
