Any iPhone or iPad Pro with Face ID (TrueDepth front camera) running iOS 17 or later.
Check that: glasses are removed and hair is pulled off the forehead; your face is 30–40 cm from the phone; the phone is held vertically (cross-hair turns green); you look at the red dot next to the camera rather than at the screen; lighting is even without back-light. Capture starts automatically once every check passes.
Far PD is derived from the eye rotation centres, refined by multi-frame fusion and optional ISO 7810 card scale verification. Segment height is a simulation based on your virtual frame settings; final fitting values should be confirmed by an eye-care professional with the actual frame. The App does not provide medical diagnosis.
