About

StrideMirror

Features
Read full description

StrideMirror turns a short walking clip into a clear picture of how you move — entirely on your phone. Record 10–30 seconds of yourself walking, and StrideMirror uses Apple's on-device body-pose detection to extract movement metrics: cadence, stride time, step symmetry, knee flexion, trunk lean, and more. Watch how your walking rhythm changes over time on a simple trend chart. Built for people who are curious about their own movement — runners checking form, older adults staying active, anyone recovering from a long sit at a desk. StrideMirror is a personal observation tool, not a medical device, and is not intended to diagnose, treat, or prevent any condition. WHY STRIDEMIRROR • Private by design — all video processing happens on your iPhone. Nothing is ever uploaded. There is no account to create, no email to give, no analytics, no advertising IDs. • Truly free — no in-app purchases, no subscriptions, no ads. Ever. • On-device intelligence — uses Apple Vision's body-pose model. No internet connection required after install. • Bilingual — full English and Simplified Chinese support. HOW IT WORKS 1. Film. Prop your phone up about 3 meters away and record yourself walking past it for 10–30 seconds, ideally from the side. 2. Analyze. Tap import. The app finds your body keypoints frame-by-frame and computes spatial-temporal gait parameters. 3. Observe. Get a single overall walking-function score (0–4), a balance reference, and a breakdown of individual metrics. Save it to your local history and watch the trend. WHAT YOU SEE • Cadence (steps per minute) • Stride time and stride-time variability • Step and swing symmetry • Knee flexion range • Trunk lean and lateral sway • Arm-swing asymmetry • A simple "walking function" score from 0 (steady) to 4 (markedly unsteady) • Trend chart of your most recent walks PRIVACY StrideMirror is built around one rule: your video never leaves your phone. The app has no backend. There are no servers, no cloud, no syncing. Your walking history lives in this app's local storage and goes away if you delete the app. Read the full policy at https://ieaglez.github.io/StrideMirror/privacy.html LIMITATIONS StrideMirror works best with side-view clips of normal indoor or outdoor walking. Loose clothing, very low light, multiple people in frame, or extreme camera angles will reduce accuracy. The app may decline to score a clip when it cannot detect a clear walking pattern. NOT MEDICAL ADVICE StrideMirror is for personal interest only. It does not diagnose any condition and is not a substitute for evaluation by a qualified healthcare professional. If you have any concerns about your walking or balance, please consult a clinician. REQUIREMENTS • iOS 17 or later • A real device with the Apple Vision body-pose model (the iOS Simulator is not supported) We hope you enjoy watching how you move.
