Read this before you use it

• It is a screening aid, not a biomechanics lab. One camera, one angle. It narrows down where to look. It does not diagnose anything.
• It is not medical advice and does not treat, diagnose or assess the risk of any injury. It measures kicking technique. Pain, swelling, or a joint that gives way is a physiotherapist’s job today, not an app’s.
• It tells you when it cannot read a clip. Filmed from behind, half the body out of frame, too dark — it says so instead of inventing a score. A confident wrong number is the failure mode that actually matters here.
• Angles from a single camera carry error. Treat a borderline number as borderline and re-film from a better angle before acting on it.
