Prop your phone side-on, pick a drill, and do your reps. Each one is counted and judged as it finishes — either “Good” or the one thing to fix on the next rep, called out loud enough to hear from where you are standing.

There is no chatbot here and nothing is generated. A pose model finds your joints in each frame; every verdict after that is measurement — angles, heights and timings against a number set for that drill.

It needs the camera, and the first load pulls down the pose model, so give it a moment on mobile data.

Alpha, under heavy development. Drills are still being calibrated, counts and verdicts can be wrong, and things may not work as expected.

Everything runs on this device. The video never leaves it, nothing is uploaded, and there is no account.
