The device samples motion, extracts fatigue-relevant features, and streams the result to the companion app in real time.
The onboard IMU captures 6-axis motion data — accelerometer + gyroscope — at high frequency. Every 500 ms window of raw LSB data is processed on-device.
7 fatigue-relevant features are computed: Accel RMS, Accel Peak, Cadence CV, Jerk Proxy, Event Count, Gyro RMS, Gyro Peak — per your sport and placement.
Each metric is z-scored against your session baseline. Weighted by sport and placement, the combined score maps to WARMING_UP / GREEN / AMBER / RED.
Fatigue state, raw telemetry, and configuration stream live to the iOS companion app over BLE. The device has no display — the app is the interface.
Real-time fatigue scoring for every athlete — from elite performance centres to solo training sessions.
