FormCheck: AI Gym Coach

FormCheck turns your iPhone into a real-time lifting form coach. Prop up your phone, start a set, and watch a live skeleton track every rep — scoring your depth, bar path, and technique as you lift. HOW IT WORKS • Prop your phone side-on, stand back, and lift • A live skeleton overlays your body and counts every rep • Get instant voice coaching — "go deeper," "keep the bar close," "push your knees out" • See a form grade for every rep and every set • Export slow-mo replays with your skeleton and score burned in — perfect for sharing THREE BIG LIFTS • Squat — depth, forward lean, knee tracking, tempo • Deadlift — hip timing, bar path, lockout • Bench — chest touch, bounce, lockout WATCH YOURSELF IMPROVE Every set is saved with a grade and score. A progress chart shows your form climbinge actually getting better, not just stronger. 100% ON YOUR PHONE There is no server.
