Point your webcam at yourself. The model tracks 33 body landmarks per frame, measures your joint angles as you move, counts every rep, and tells you out loud when your form breaks down — no wearables, no guesswork.
Nothing here needs a sensor strapped to your wrist. It's all read straight from the camera feed, frame by frame.
Measures the angle at your knees, hips, elbows, and back on every single frame, not just at the top or bottom of a rep.
Recognizes the full range of motion for each exercise and counts a rep only when you actually complete it.
Flags rounding backs, caving knees, and half reps the moment they happen, while the movement is still in frame.
Says what's wrong out loud — "knees in," "go deeper" — so you never have to break form to check a screen.
Named "reps" because that's genuinely what happens — each stage below runs again, every single rep you perform.
Your browser sends live webcam video straight to the model — nothing is recorded or uploaded anywhere.
A pose model built on MediaPipe locates your shoulders, elbows, hips, knees, and ankles in every frame.
Those landmarks are turned into real angles — knee flexion, hip hinge, elbow bend — and compared to a good rep.
Feedback is spoken back to you and your rep count and set progress update on screen, all in the same second.
Runs on an open pose-estimation model and a handful of well-tested tools — no proprietary hardware, no app to install.
