FormMirror

FormMirror is a mobile AI app for individual-sport athletes who train alone and don’t have a coach watching. You record short clips (10–30 seconds) of a movement—tennis serve, golf swing, squat, sprint start, jump rope, shadowboxing—and the app auto-trims, stabilizes, and analyzes body positions over time. It flags 2–3 high-impact issues (e.g., hip rotation timing, knee valgus, elbow drop) and gives simple, sport-specific drills to fix them. It also creates side-by-side comparisons against your own best reps, not unrealistic pro footage. The goal is not perfect biomechanics; it’s consistent, measurable improvement with minimal friction. Brutal reality: accuracy will be “good enough” for common patterns, not elite-level coaching. The MVP should focus on a few movements per sport and expand only when the model and labeling quality are proven.
