RepTracker: AI Form Video Analysis
AI analyzes gym workout videos in real-time to detect form errors and auto-logs reps, sets, and weight for solo lifters
The Problem
Solo gym-goers can't safely assess their own form without a spotter, and manually logging workouts is tedious and error-prone. Existing form-correction apps require manual setup or only work with specific equipment, missing the casual lifter market.
Target Audience
Independent gym members (ages 18-45) who train alone 3+ days/week and use phones to record sets but skip form feedback due to friction
Why Now?
Vision APIs are now cheap and fast enough to run on-device; lifters normalized recording gym videos post-COVID; AI video analysis just became accessible to indie builders
What's Missing
Existing solutions either focus on coaching feedback (slow, expensive) or rep-counting (ignore form), not both. No app combines real-time form warnings with instant workout logging for the solo lifter workflow.
