A focused tool for motion data collection ChironMotion Capture is a lightweight iOS application designed for motion research and sports science data collection. Its sole purpose is to record raw IMU (Inertial Measurement Unit) data from the iPhone and export it as CSV files for use in external analysis environments. This app does not perform analysis, calculations, scoring, or interpretation of the recorded data. High-Frequency IMU Data Capture Records acceleration and gyroscope data using built-in iPhone sensors Fixed sampling rate suitable for research and motion studies Applicable to jumping, walking, running, and other movements CSV Data Export Exports raw sensor data in structured CSV format Compatible with Python, MATLAB, R, and other analysis platforms Can be used with external tools such as ChironMotion AI Bilingual Interface Supports Traditional Chinese and English Designed for international and professional use Clean, Purpose-Driven Design No charts, metrics, or analysis results Focused exclusively on data capture and export Optimized for quick use in research or training settings Usage Recommendations & Safety For data quality and safety: Secure the phone firmly around the sacral–lumbar region Perform adequate warm-up before jumping or high-intensity movements Conduct tests in a safe, flat, and obstacle-free environment Disclaimer This app is intended solely for motion data capture and export It does not provide medical diagnosis, treatment, training advice, or analysis Exported data is for research and professional use only
