ReMotion Sees What You Can't Measure top speed and analyze sprint mechanics from any iPhone. No gates, no radar, no expensive gear — just your phone and a couple of cones. Sprinting can feel fine while patterns build underneath the surface. Those hidden patterns create two problems at once: performance risk (wasted reps, slower progress) and injury risk (compensations that add up over time). ReMotion helps you see what's happening sooner, so you can correct earlier and keep training consistent. Record a sprint in Live Mode or upload a video. ReMotion clocks how fast the athlete is really moving and breaks down key sprint phases and body positions — then gives you clear, coaching-style feedback so you know what to work on first. What you can do with ReMotion: - Measure top speed and velocity from a single iPhone — no timing gates required - Analyze stride and sprint mechanics from video (Live Mode or Upload) - See phase-by-phase insights (Toe-Off, Strike, Touchdown, Full Support, and more) - View the key angles and markers that drive your results - Get training-focused movement flags and pattern insights (no medical claims) - Receive athlete cues and coach-style cues you can apply right away - Export and share results for review and communication (when available in your plan) Who it's for: - Coaches managing multiple athletes or groups who want faster feedback and clearer communication - Athletes who want simple, actionable technique improvements between sessions - Parents who want clarity on what to work on between practices Plans ReMotion Pro unlocks full speed measurement, stride analysis, and advanced tools for development and review. Available as a weekly or annual subscription Important note: ReMotion is for training and educational purposes only. It does not provide medical advice or diagnose injuries. If you choose to upgrade to our subscription, payment will be charged to your Apple account, and your account will be charged 24 hours before the end of the current period.
