RunForm 3D

Film from the side. Get a Form Efficiency estimate from cadence, vertical oscillation, ground contact time and more.

RunForm 3D analyzes your running form using monocular 3D pose estimation — just film yourself from the side with your iPhone.

• Automatic ground-contact detection
• Key determinants of running economy: cadence, vertical oscillation, ground contact time and more
• Per-factor good / acceptable / needs-improvement zones
• Form Efficiency Score (0-100, an estimated proxy) with a confidence label

How to use: enter your height (optionally target pace), fix your phone and film from the side so the whole body fits, run a few steps, then stop to analyze.

Important: The app interface is in Japanese. Scores and metrics are estimates derived from motion, NOT direct measurements of oxygen uptake (VO2) or running economy. This is not a medical device and does not diagnose or guarantee any outcome. Analysis runs on-device.
