3-axis motion detection for activity, fall detection, and sleep analysis
Wrist temperature monitoring for cycle tracking and fever detection
Advanced Capabilities
Red and infrared light measure oxygen saturation levels
Multi-sensor fusion identifies REM, deep, and light sleep phases
AI algorithms detect atrial fibrillation and other arrhythmias
Machine learning identifies falls and automatically calls for help
Hidden Health Features Most People Never Discover
Advanced Heart Rate Analytics
Heart Rate Variability (HRV) Tracking:
- • Measures autonomic nervous system balance
- • Indicates stress, recovery, and training readiness
- • Tracks during sleep for optimal measurements
- • Correlates with overall health and longevity
- Hidden Access: Settings → Privacy → Analytics → Share Analytics Data
Resting Heart Rate Trends:
