About
New Health Insights:
Vitality Age: A new bio-age metric that compares your real age against your health data (HRV, RHR, Sleep, and Activity) to see if your body is "younger" or "older" than you are.
Cycle Tracking: Integrated Cycle Phase tracking (Follicular vs. Luteal) to give you training advice based on your hormonal cycle.
Sickness Detection (Internal Load Alert): The app now detects when your body is under strain (high RHR/Respiratory Rate) despite low activity, warning you of potential illness or overtraining.
Daily Stress Score: A new 0-100 "Stress Load" bar that visualizes your physiological stress based on HRV.
EKG Integration: View your latest Apple Watch EKG classification directly on the dashboard.
