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.

Verdict
The clearest difference is in-app purchases: Overlay at none against StrideCheck's 2. StrideCheck's advantage is ads (none vs shown) and iOS requirement (16.4 vs 18.4). On price and device support there is nothing between them.
