How Fit Play counts the Wall Sit 📱
Fit Play tracks the position and angles of your joints in real time. The clock runs only while you hold the position shown above; if your form breaks, the timer pauses and picks up again once you are back in position.
Joint angles read from the "Hold" sample photo: knee about 91°, hip about 92°, elbow about 20°.
These come from a single photo, so they vary with body proportions and camera angle.
Recognition is most stable when the phone stands upright 2–3 meters away and your whole body, head to toe, is in the frame.
