Running Form Analysis Web App (MVP)

Language

Browser-only (no upload): analyzes locally with simple rules to estimate overstride / knee extension / trunk lean / foot strike / leg retraction .

Heads up: phone analysis can be slow and battery-heavy. For a faster experience, use a laptop/desktop or an iPad Pro/mini. Everything runs locally for privacy and zero server/storage cost.

1) Requirements & Example

Requirements (minimum for analysis)
  • Side view, single runner, and consistent direction (left-to-right or right-to-left).
  • 1080p or higher at 30 fps (video your browser can decode), or 240 fps slow-mo (iPhone Slo-mo).
  • At least 3 seconds of real-time running (4-6 strides).
Example: Good capture framing
Example only. Follow this framing for your own video.

2) Input Video

        Suggested capture: phone fixed, camera height near hip, side view, good lighting, subject fills ~60-90% of
        frame height.
