Rapsy

Rapsy turns your phone into an AI-powered fitness companion that works like a virtual personal trainer, automatically counting reps, giving real-time voice guidance, and estimating calorie burn so you can focus on the workout rather than logging it. Using on-device pose detection, Rapsy maps joint angles and movement through your device camera to monitor form and consistency during home or gym sessions, and it processes video locally for privacy. If you want hands-free tracking, clear vocal feedback, and per-session analytics without sharing video to the cloud, Rapsy is built to simplify and motivate your training.
