Upload a short training clip and see your technique analysed straight away – free and without signing up. Pose detection runs on your own device; only the selected clip section and the measured values are sent for the coaching report.
If the data is not good enough (bad camera angle, clip too short, person not detectable), the report says so openly and asks for a better recording instead of claiming a score. The report is not a substitute for medical or physiotherapeutic advice.
