RepCount: AI Form Spotter for Lifting
Phone camera app that counts reps and flags bad form in real-time using pose detection, for solo lifters without gym buddies or trainers
The Problem
Solo weightlifters can't tell if they're doing exercises correctly without paying for a trainer or recording themselves awkwardly. They miss reps, cheat form, and plateau because they have no feedback loop. Existing fitness apps require manual logging and don't actually watch you lift.
Target Audience
Home gym enthusiasts and budget-conscious lifters (18-45) who lift alone 3-5x per week but don't have $150/month for a personal trainer
Why Now?
Phone cameras are now good enough for pose detection without cloud processing; on-device ML models run smoothly; home gym adoption is sticky post-pandemic
What's Missing
Existing apps either require manual rep counting or are AI-powered but cost $20+/month with poor UX. There's no simple, free/cheap solution that actually watches your form live and says 'stop, your elbows are flaring'
