Know YourLimits...BeforeThey KnowYou...
A wearable sensor that scores your fatigue state in real time, streaming live performance telemetry to your smartphone. No display. No guesswork.
Four States.
Zero Guesswork.
Baseline adapting. The sensor is learning your motion signature for this session. No fatigue scoring yet.
Performing within normal range. All metrics within z-score tolerance of your session baseline. You're good to push.
Fatigue accumulating. One or more metrics drifting from baseline. Manage intensity and monitor closely.
High fatigue load detected. Significant deviation across weighted metrics. Reduce output to avoid injury risk.
7 Signals.
One Score.
Each metric captures a distinct physiological fatigue mechanism. Together, weighted by your sport and sensor placement, they form a precise composite score.
Root-mean-square of acceleration magnitude. A fatigued athlete shows gradually reducing overall output — falling RMS in sustained sports is a strong muscular fatigue signal.
Maximum single-sample acceleration in the window. Tracks whether an athlete is landing harder (rising) or losing explosiveness (falling) — distinguishing injury risk from power loss.
Coefficient of variation of stride/stroke tempo. Rising CV means the nervous system is struggling to hold the motor pattern — often detectable before the athlete feels it.
Rate of change of acceleration between samples. Fatigue disrupts neuromuscular coordination — producing choppier motion, degraded shock absorption, and compensation patterns.
Samples exceeding a configurable acceleration threshold per window. Approximates step count, pedal strokes, or reps — showing explosive output decay and cadence drop.
RMS of angular velocity. Fatigue reduces rotational range of motion to conserve energy (falls) or causes loss-of-control excess rotation (rises). Z-score captures both.
Maximum single-sample angular velocity. Captures peak swing speed in racket sports — typically drops before average velocity does. Rising peak + falling RMS signals erratic compensatory motion.

Sagittal-plane gait — rotation is secondary. Cadence drop and output reduction are the primary signals.

No screen. No buttons to navigate. Just a status LED and a single button. Every configuration and readout lives in the iOS companion app over BLE — keeping the device featherlight and distraction-free.
