Read full description

ChironMotion Vison is an iOS application designed for structured jump-movement analysis using camera-based motion capture and on-device computation. The app supports three standard jump protocols: CMJ, SJ, and DJ. Users can create a personal profile, enter basic body information, and select the appropriate test protocol before each session. A built-in calibration process helps improve consistency before testing begins. During recording, the app captures movement through the camera and analyzes the jump sequence automatically. Key phases such as takeoff and landing are identified to support performance evaluation. The app calculates core biomechanics metrics, including jump height, flight time, RSI, and related movement indicators. Protocol-specific metrics are also presented to help users review jump quality in more detail. Results are displayed in a clear interface with summary cards and visual charts for easier interpretation. The app also supports offline video analysis for imported high-frame-rate footage. All analysis is performed locally on the device to help protect user privacy. ChironMotion Vison is intended for training, performance review, and educational reference, and is not designed for medical diagnosis or treatment.
