A photo becomes real angles, on your own device.
Not a guess dressed up as a score. Real geometry, measured on device, stored alongside the score so a trend can be drawn in actual degrees.
Three real measurements
Head angle, trunk lean, hip offset — genuine geometry from body pose, not a stylised illustration standing in for a number.
A bad photo is rejected, not scored
A front-on photo that can't actually measure the angles gets a plain, specific reason instead of being scored as if it could.
Drills that follow the finding
Real drills for what's actually measured as off, not a generic stretching routine everyone in the app gets handed.
It stands alone, and stays that way.
Posture, on its own
Nothing else in the app currently reads posture data — it's a complete tool by itself, not half of an integration waiting for the other half.
Raw angles, kept for later
Stored in degrees rather than just the final score, so a threshold revised later can be applied to history that already exists.
