ChironMotion is a professional-grade motion analysis tool designed for coaches, athletes, and sports scientists. Leveraging advanced iPhone sensors and a proprietary physics engine, it delivers lab-quality jump metrics simply by securing your phone to your waist. Key Features: Comprehensive Test Protocols: Countermovement Jump (CMJ): Measure lower-limb power and monitor neuromuscular fatigue. Squat Jump (SJ): Assess pure concentric explosive strength. Drop Jump (DJ): Analyze Reactive Strength Index (RSI) and plyometric performance. Single Leg Stance (SLS): Evaluate bilateral symmetry and dynamic balance stability. Precise Biomechanical Metrics: Instantly obtain Jump Height, Flight Time, RSI, Peak Power, Rate of Force Development (RFD), and Landing Impact. High-frequency 200Hz sampling captures movement details invisible to the naked eye. AI-Powered Insights: Get personalized training advice from three distinct AI personas: Scientific Expert, Enthusiastic Coach, and Toxic Coach. Go beyond numbers - understand what your data actually means for your training.

About

Explosive Athlete

Read full description

Explosive Athlete turns your Explosive Belt sensor into a complete jump-testing and velocity-based-training lab. JUMP TESTING Jump height, flight time, takeoff velocity, peak force, mRSI, eccentric & concentric velocity and the shape of every jump - measured at 500 samples per second. CMJ, squat jump, Abalakov, approach jumps and your own custom types. Wear it in practice: every jump counted and measured automatically. BAR VELOCITY Auto-detected reps with peak and mean concentric velocity, range of motion, velocity-loss tracking with configurable set-stop alerts, training zones, bar path and full velocity/power curves - plus explosive-profile metrics like time-to-peak-velocity, POP-100 and the eccentric acceleration index. GYM MODE Huge numbers readable from across the floor, with instant sound feedback on every rep and jump. TEAM Rosters, athlete profiles with bests and trends, readiness flags, Force-Velocity profiling, session history, PDF reports, CSV export. Everything stays on your device - no accounts, no subscriptions. Requires an Explosive Belt sensor (Bluetooth) for live measurement. Browsing, team management, history and manual records work without hardware.
