Range — Support

No. "Set the angle by hand" opens the same protractor with nothing behind it and saves a real measurement. Two of the eight movements — neck rotation and ankle dorsiflexion — always work this way, because Apple's pose model has no chin or toe landmark to find.

It is read on the device by Apple's Vision framework to place the three markers, and then discarded. It is never stored, never added to your library and never uploaded. Only the angle is saved.

The photo picker runs outside the app, so Range receives one chosen image and never gets access to your library. There is no camera code, so there is no camera prompt either.

No. It measures an angle and records how it changed. It does not diagnose, treat or assess anything. The typical ranges it shows are published adult population averages shown as a reference, never as a target. If something hurts, see a physiotherapist or a doctor.

Drag them. The detector is a starting point, not a verdict — the degrees readout follows your finger, and a measurement you corrected by hand is just as real as a detected one.

Free measures every movement, compares with last time and follows two movements over time. Pro adds all eight movements on both sides, the complete history, and the left-against-right comparison.
