Your Apple Watch just became a more powerful health dashboard. The latest MyBioAge update brings all four key metrics to your wrist—biological age, recovery, stress resilience, and circadian alignment—each with color-coded status indicators for instant comprehension.

Four metrics at a glance

No need to pull out your iPhone. Your Apple Watch now displays:

MyBioAge Index — Your biological age with trend direction and status color.
Recovery Capacity — Ready, Moderate, or Limited indicators based on your 4-signal breakdown.
Stress Resilience — Your stress adaptation capacity (0-100) with color-coded zones.
Circadian Alignment — How well your rhythms sync with your natural clock (0-100).

Color-coded feedback

Each metric shows green, yellow, or red status indicators:

Green — You're in the optimal range. Keep doing what you're doing.
Yellow — Room for improvement. Consider checking the AI Coach for specific insights.
Red — Needs attention. Review your trends and adjust your approach.

This instant visual feedback means you can check your status in seconds. A quick glance at your wrist tells you whether you're on track or need to adjust today's plans.

Backed by 6 months of data

The scores on your Apple Watch aren't based on today's data alone. They're calculated from 6 months of your health history, synced from your iPhone. This means the status indicators reflect genuine trends, not day-to-day noise.

Works offline

Your Apple Watch caches your latest scores via Bluetooth. You can check your biological age, recovery, stress resilience, and circadian alignment even when your iPhone is out of range. Manual refresh updates the data when you're connected.

Practical use cases

The four-metric watch display is useful throughout your day:

Morning check — Glance at recovery and stress resilience before deciding on today's workout intensity.
Pre-workout — Yellow or red recovery? Consider a lighter session.
Evening review — Check circadian alignment to see if your schedule is on track.
Weekly planning — Green across the board? You have capacity for challenging sessions.
