Left-Right Balance & Symmetry Test (Camera)
Most people are stronger or more mobile on one side. This test uses your camera to measure it. Choose single-leg balance (hold time and sway for each leg), squat symmetry (left and right knee angles and sideways hip shift), overhead reach (how high each arm goes) or push-up symmetry (left and right elbow bend).
You get a clear left-vs-right result with the percentage difference, a plain-English verdict and exercises to correct the weaker side. Small differences are normal; larger ones are worth working on.

Frequently asked questions
Is a 10% difference bad?
No. Many people differ by 5 to 10%. Larger gaps are worth training and, if painful, checking with a professional.
Does it work from any camera angle?
Yes. Joint angles are measured in 3D, so front, side and diagonal views give the same readings. Keep the camera upright and your whole body in the picture.
Is my video uploaded?
No. The pose detection runs inside your browser. Nothing is recorded, uploaded or stored unless you choose to save a replay on your own device.
Is it free and private?
