# CoachAI

> CoachAI turns your iPhone into a personal fitness coach that actually watches you work out. Prop the phone up, and it uses the camera and the LiDAR sensor to track your motion in real time, counting reps, keeping tempo, and flagging when your form starts to break down. The result is hands-free feedback during a set, the sort of correction you would normally need a trainer standing next to you to get. The privacy angle is the part worth underlining. All of the motion processing happens on the device itself, and the company says camera data is never uploaded, so you are not streaming video of your home workouts to someone else's server. Workouts adapt based on how you actually performed rather than a fixed plan. For anyone who trains alone and worries they are quietly reinforcing bad habits, it is a genuinely useful application of the depth-sensing hardware that has been sitting in high-end iPhones for years, put to a purpose most people never use it for.
