Film one slow rep from the side. Your video never leaves your phone. You get a plain description of what your body did and what to look at — not a green light to add weight, and no substitute for a coach watching you in person. Free. Bodyweight or very light load only.
Bodyweight only. Stop if anything hurts.

This measures joint angles from one camera angle. It cannot see how your knees track side to side, whether your spine is rounding, or how your weight sits across your feet — the things that matter most for staying safe under load. It is not coaching, not a clearance to add weight, and not medical advice. If anything here concerns you, or if a movement hurts, have a qualified coach or physiotherapist watch you in person.
Reading every frame of your clip.
Your video is read frame by frame on your own phone. It never travels to our server, is never stored, and is never seen by anyone — including us.
There is no database and no account. Only about a dozen anonymous numbers, like joint angles and timings, are sent to be turned into coaching. Close this page and even those are gone.
Most apps like this upload your video and keep it. We think a video of your kid belongs to you.
