REPPEN

REPPEN is the adaptive strength coach that responds to your live heart rate.

LIVE HEART RATE, BUILT IN Connect Apple Health to stream live BPM from your Apple Watch (or any app that writes to Apple Health) during warmups and working sets. REPPEN gates progressions on how hard your body is actually working — not just what your last session said.

PERIODIZATION THAT LEARNS YOU REPPEN builds weekly programs around your goals, your equipment, and your recovery. Hypertrophy, strength, and deload phases flow automatically. Auto-tracking implicit 1RM keeps every prescription accurate as you get stronger.

STRENGTH + CARDIO IN ONE APP Every set, every interval, one clean interface. Rest timers, RPE tracking, and smart progressions on the lifts that matter. HIIT, steady-state, and zone-based cardio sessions when you need them.

REST IS THE WORK Built-in deload weeks and recovery prompts so you keep training hard without burning out. Readiness scoring informed by your real HR and session history.

SEE YOUR PROGRESS Weekly volume, intensity trends, personal records, and friend streaks. The numbers that actually tell you you're getting stronger.

BUILT FOR YOUR SPORT 60-second setup. Pick your split, your frequency, your phase length. REPPEN does the programming.
