Rapsy

Rapsy turns your smartphone into an AI-powered personal trainer that watches your form, counts repetitions, speaks real-time guidance and estimates calories from each session. Using on-device pose detection through the camera, Rapsy maps joint angles, tracks rep totals for more than 70 exercises, and times isometric holds without requiring manual logging. Privacy-focused users will appreciate that all video is processed locally and sessions work offline, while exercisers looking for accurate gym estimates can enter lifted weights to refine calorie calculations. Rapsy is aimed at people who want an automated, hands-free way to track workouts at home or in the gym.
