Use Standard mode for quick answers and Deep Research mode for long-term health analysis.
COMPREHENSIVE SLEEP TRACKING & DAILY REPORTS
Sleep Index breaks down exactly how you slept (Total Duration, REM, Deep, and Light Stages), Resting Heart Rate, and restfulness for a full picture of how well your body rested overnight and what to do to improve it.
STRESS MONITORING AGAINST YOUR BODY CLOCK
Stress Rhythm tracks how your heart responds across the day, mapped against your circadian rhythm for a clear and continuous read of your state. Understand if you're stimulated, relaxed, or stressed and decide the day's load on your system.
CYCLE & OVULATION TRACKING
Cycle tracking, ovulation prediction and confirmation, unique Cycle Flags, and pregnancy insights – all powered by your ring data. The Women's Health PowerPlug gives you a proactive, personalized view of your reproductive health across every phase.
RECOVERY THAT ADAPTS IN REAL-TIME
Dynamic Recovery reads your readiness moment to moment using Heart Rate Variability (HRV), skin temperature, and heart rate. It recalibrates your score as you take action so you always know when to push and when to pause.
PERFORMANCE BY DESIGN
