# CoachAI

> CoachAI turns an iPhone into a form checker for your workouts. Point the camera at yourself and it watches your movement rep by rep, analyzing your technique and offering real-time feedback and corrections the way a trainer standing beside you might. The promise is to catch the small breakdowns in posture and range of motion that cause injuries and stall progress, without paying for a session every time you exercise. On-device pose tracking has quietly gotten good enough to make this kind of thing feel plausible, reading joint positions from an ordinary phone video and flagging when a squat is shallow or a back is rounding. CoachAI packages that into a fitness coach aimed at regular people rather than athletes with lab access. As with any automated coaching, it is a helpful guide rather than a substitute for professional advice, especially with heavy lifts or existing injuries. But as a free-ranging second set of eyes on your form, it is a neat example of applied computer vision doing something practical in your living room.
