About this app
RepZen automatically counts your bodyweight workout reps using your Apple Watch's motion sensors — no taps, no fumbling with your phone. Push-ups, sit-ups, squats, pull-ups, jumping jacks, lunges, and more. RepZen picks the right motion signal for each exercise, so it counts the way the movement actually happens. A hands-free voice coach calls out every rep and cheers you on, narrates your countdown and rest periods, and auto-advances through your plan — all from your wrist. Add music from your iPhone and it plays while your Watch does the counting. • Automatic rep counting from Apple Watch motion • Voice coach: spoken counts, encouragement, narrated rest • Build workout plans with sets, reps, and rest • Per-exercise sensitivity tuning with on-screen guidance • Syncs workouts to Apple Health • No accounts, no ads — your data stays on your device Put your phone down. Just move. RepZen keeps count.
