POSTURE
Posture is the number nobody tracks because nobody can see themselves. Two photos — standing relaxed, front-on and side-on — and The Coach gives you the read: what's visible in plain language, what looks solid, and three or four daily habits actually worth your time. Then you recheck monthly, because posture moves in weeks, not days.
It will tell you the head sits forward of the shoulder line; it will never name a condition or play physiotherapist, because a photo can't carry that weight. Persistent pain belongs with a professional — and it says so.
Chin tucks, a doorway stretch, screen height, sit-stand breaks — small daily habits matched to what it saw, each with a one-line how. The Coach occasionally checks whether you're doing them.
One check a day, photos analysed and never stored, and a dated history so you can watch the read change month to month. No moralising — posture is information, not a verdict.
