FormFit

Lifting alone is how people get hurt. Fatigue breaks your form rep by rep — knees cave, backs round — and nobody's there to call it. A personal trainer fixes that, at $100 an hour. FORMFIT does it from the camera you already own. Point your phone at your set and the app tracks your skeleton live at 25fps. It counts every rep (and refuses to count walking around or fixing your hair), scores your knee, hip and back angles against exercise-specific targets, and fuses rep-velocity decay with form loss into a single effort score — so you know when the set is actually done, not just when it feels done. Coaching cues land mid-set, when they still matter. When you end the workout, an AI coach reads the whole set's telemetry and writes your debrief: what held up, what broke, what to change next session. Every claim traces back to a number in the rep table — proof, not vibes. Then it goes social. Every set becomes a post with your form and effort scores, so friends can follow your training and compete on quality, not just weight. Strava, for lifting.
