Apple Watch Health Dashboard: Index, Recovery and Daily Metrics
See which My Bio Age scores appear on Apple Watch, how status colours work and when the companion refreshes from your iPhone.
By My Bio Age
The My Bio Age Apple Watch companion gives you a compact view of the scores calculated on your iPhone. Its current dashboard shows the MyBioAge Index™ and four daily metrics: Recovery, Training Load, Stress Resilience and Circadian Alignment.
What each item tells you
- MyBioAge Index™: the latest complete weekly wellness estimate, with its age difference and confidence information when available.
- Recovery: a summary of available recovery signals.
- Training Load: the relationship between recent activity and the longer activity window.
- Stress Resilience: a daily composite of HRV, resting heart rate, sleep and activity signals.
- Circadian Alignment: a summary of recorded timing and regularity patterns.
The Index and the daily metrics have different time windows. They are not all six-month averages, and they need not move together.
Read the label as well as the colour
Colours make categories easier to scan, but each metric has its own thresholds. A green category is not medical clearance for a hard workout. Compare the number and status with how you feel and with the underlying records on your iPhone.
When does Apple Watch update?
The phone calculates the scores. Open My Bio Age on your iPhone and allow the refresh to finish, then open the watch companion while the phone is reachable. The watch requests the latest values. It does not independently recalculate the Index from its own sensor readings.
When the phone is out of reach, the watch can show cached values it previously received. Those values are useful for reference but may be older than the current day. Check the displayed freshness information before treating them as a new update.
If a score is missing
Check the same score on the phone first. A missing input or insufficient data can leave a score unavailable on both devices. If the phone has current values but the watch does not, keep both apps open and check that the devices can communicate.
Use the watch for a quick check and the iPhone detail views for context. My Bio Age offers wellness information, not diagnosis, and a colour alone should never determine a health decision.
Start on iPhone, then use the included Apple Watch companion for quick score checks. Download My Bio Age free on the App Store. The iPhone app is completely free, with no in-app purchases, subscription or account required. Your health data is processed privately on your iPhone.
