Hey Product Hunt! 👋 I'm Yao, a fitness enthusiast and indie maker. I built RunBodyCheck because I was frustrated by how inaccessible proper gait analysis is. Most runners end up with knee or IT band injuries simply because they buy the wrong type of shoes for their natural pronation angle. Traditionally, getting your gait tested meant paying for a clinical treadmill session. I wanted to democratize this process. RunBodyCheck is a completely free, browser-based tool that uses on-device computer vision to analyze your lower-limb biomechanics. Here is how it works: Prop your phone against a wall. Stand in the frame. The AI calculates your exact pronation angle in real-time and matches you with the correct shoe category (Neutral, Stability, or Motion Control). Privacy is critical for body scanning, so 100% of the video processing happens locally on your device. No video data is ever sent to a cloud server. I would love for you to try it out with your next run in mind. Any feedback on the UI, the AI tracking accuracy, or feature requests would be massively appreciated!
