Advanced Sleep Tracking
Get a comprehensive overview of your sleep with metrics including sleep stages (light, deep, REM), sleep score, heart rate variability (HRV) status, and breathing data. These insights help you better understand how well your body recovers each night.

Seamless Garmin Connect Integration
All data automatically syncs to the Garmin Connect app, where you can view trends, insights, and progress. Combine with data from a compatible Garmin smartwatch or heart rate monitor for a complete health and fitness overview.
Breathing and Pulse Ox Monitoring
Track your nighttime breathing patterns and blood oxygen saturation levels to understand respiratory changes during sleep, potentially indicating issues like sleep disturbances or altitude acclimation.
Skin Temperature Tracking

Smart Wake Alarm
Wake up feeling refreshed with a gentle vibration alarm that activates during the lightest stage of your sleep cycle within a set time window.
Women’s Health Insights
Skin temperature data supports better menstrual cycle tracking and past ovulation estimation. Use the Garmin Connect app for additional guidance on pregnancy, exercise, and nutrition.

See your energy levels rise and fall throughout the night and day. When paired with a compatible Garmin smartwatch, this feature gives you a full 24-hour picture of your body’s readiness.
