Prop your phone, hit record. The camera reads your squat, deadlift, and bench in real time and tells you what to fix, set by set.
On-device, on the iPhone you already own.
Uses the camera and Apple's Vision framework. No extra hardware, no special studio.

Built for the lifts that matter most.
Squat, deadlift, and bench at launch; more compounds rolling out.
AI Form Check is training guidance, not medical advice. If something hurts, stop and talk to a qualified professional.
