About StrideCheck: Running Form AI
Film 10 seconds of your run. StrideCheck's AI reads your stride like a coach and hands you a form score, your #1 fix, and a 2-week plan, all grounded in peer-reviewed research. HOW IT WORKS 1. Prop your phone side-on and record 10 seconds of running (treadmill or road), or upload a clip. 2. AI tracking measures 33 body points in every frame. 3. Get your form score, every metric explained, and one clear fix with drills. WHAT GETS MEASURED - Cadence (steps per minute), matched to your pace - Landing position and overstriding - Vertical bounce - Posture and trunk lean - Knee bend at landing - Foot strike (precise with slo-mo video) WHY RUNNERS TRUST IT - Evidence first: recommendations follow published research, like gradual 5-10% cadence changes shown to cut running injuries 62% in a randomized trial (Chan 2018). - No fads: no barefoot dogma, no "one perfect form". If nothing needs fixing, StrideCheck says so. - Honest measurements: bad filming angles and unclear clips are rejected with specific instructions before any payment. - Private: videos are analyzed and deleted from the server within 24 hours. STRIDECHECK PRO Your full report, drills, 2-week plan, history, and unlimited re-tests unlock with a subscription: $3.99/week or $24.99/year. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed in your App Store account settings.
