9月2日 的 Metric Jump 應用程式分析

Test your vertical jump like a force plate, using only the camera on your phone. Metric Jump turns your iPhone camera into a fully automatic vertical jump testing lab. No force plate, no jump mat, no wearable, no floor markers. Stand in frame, jump, and get instant, validated jump height, take off velocity, RSI, eccentric utilization ratio and symmetry scores. FULLY AUTOMATIC, START TO FINISH Most jump apps make you film in slow motion and mark the takeoff and landing frame by frame. Metric Jump does the work for you. It finds your body, detects each jump, and classifies the jump type in real time. Just jump and the app handles the rest. EVERY JUMP TYPE, CLASSIFIED IN ONE TEST Record different jumps in a single set and Metric Jump labels each rep on its own: countermovement jump (CMJ), paused squat jump, Abalakov (arm swing), and single-leg jumps (auto detects per side). Personal bests and progress stay organized by jump type. No manual tagging, no spreadsheets. ACCURATE, AND HARD TO CHEAT Metric Jump tracks your body and calculates jump height from your actual takeoff velocity, the same impulse-momentum method by lab-grade force plates. Because the number comes from the movement of your body, and not how long you hang in the air, you can't cheat the score by tucking your legs on landing the way you can on a jump mat or with flight-time based apps. A FULL ATHLETE PROFILE FROM A FEW JUMPS Metric Jump does more than print a number. Record the right jumps in one set and it calculates the comparison scores coaches actually use: - Eccentric utilisation ratio (how well you use your stretch-shortening cycle) - Arm-swing contribution (how much your arms add) - Left-right symmetry (from single-leg jumps, great for return-to-play) - Bilateral index (single-leg (L+R) versus two-leg output) - One quick test, a complete performance profile. THE METRICS THAT MATTER - Jump height, shown as a value and as a percentage of your personal best - Takeoff velocity (peak velocity) - Reactive Strength Index (RSI) - Impulse and flight time TRACK PROGRESS AND READINESS Personal bests and interactive progress charts, kept separate by jump type Trends against your rolling 6-week average A readiness and fatigue status built from your recent performance [CHECK: confirm shipped wording] Full test history for every athlete PERFECT FOR - Basketball, volleyball, AFL, and other jump-sport athletes - Athletes monitoring power, readiness, and fatigue - Physios and rehab: single-leg symmetry for return-to-play screening - Strength and conditioning coaches - Anyone who wants force-plate insight without the force-plate price GETTING STARTED IS SIMPLE - Set your height and weight once - Stand your phone up, facing you, and step into the frame - Hold still for a moment to calibrate - Jump. Get instant height, velocity, RSI, and automatic classification in real-time Jump Pro Start with a free trial. Then choose an annual subscription for unlimited testing, or grab a casual day or week pass for occasional testing. Perfect for if you only need to test every few weeks without committing to a subscription. COMING SOON Coach and multi-athlete tools (roster testing from one device and team leaderboards).
