iUvo · Methodology

How iUvo computes what you see

Every metric, score, and synthesis on iUvo is produced by a documented algorithm. Each algorithm is versioned. When we change a calculation we publish the new version here with a changelog.

anomaly scan

Current: v1

Daily anomaly scan. Flags sustained deviations of HRV / RHR / skin temp from 30d baselines and persistent SpO2 drops.

Inputs
  • hrv_rmssd
  • heart_rate
  • skin_temp
  • spo2
Outputs
  • anomaly_signal_rows
Versions
  • v1effective May 17, 2026— Initial public release.

readiness

Current: v1

Readiness composite. Compares HRV / RHR / skin-temp against 30d personal baselines and incorporates sleep + load terms.

Inputs
  • hrv_rmssd
  • heart_rate
  • skin_temp
  • sleep_efficiency
  • step_count
Outputs
  • readiness_score_0_100

sleep detection

Current: v1

Sleep window detection. Uses accelerometer-derived motion + HR drop + skin-temp pattern to bracket overnight sleep windows.

Inputs
  • heart_rate
  • skin_temp
  • motion
Outputs
  • window_start
  • window_end
  • efficiency_pct
