My Bio Age

My Bio Age turns your Apple Health data into clear, actionable biological age insights, all computed on your device. Now with an on-device AI Coach that answers your health questions using local artificial intelligence.

Your comprehensive MyBioAge Index™ combines 12 core health metrics; VO₂max, HRV, Recovery Capacity, Resting HR, Walking HR, Sleep Duration & Regularity, Active Energy, and more; into a single biological age score. Every Monday morning, you'll get an in-app digest highlighting what changed and why. Premium iOS 26 design, elegant charts, and privacy by default.

On-device AI Coach - Ask questions about your health data and get instant, personalized insights powered by AI running entirely on your iPhone. No servers, no cloud, complete privacy. Ask "What's my current VO₂max?", "Why did my HRV drop?", "How can I improve sleep?", or "What changed this week?" and get natural, easy-to-understand answers based on your actual health history.

Know your biological age - MyBioAge Index™ combines 12 scientifically-weighted health metrics to give you a comprehensive biological age estimate based on your actual health data.

Key Metrics Dashboard - Four essential metrics displayed in an elegant visualization: Recovery Capacity (cardiovascular recovery readiness), Training Load (activity balance with zone indicators), Stress Resilience (how well your body handles stress), and Circadian Alignment (daily rhythm health). Tap any metric for detailed breakdowns showing exactly what's driving each score.

Apple Watch companion - Glanceable bio age on your wrist.

Monday morning insights - A clean, in-app digest arrives every Monday at 10 AM, summarizing Mon-Sun changes and top drivers (e.g., "↑ HRV," "↓ Sleep").

Reasons, not just numbers - See which metrics moved your biological age up or down so you can act with confidence. The AI Chat Assistant can explain why changes happened and what actions to take.

Advanced precision - Track Blood Pressure with an external monitor for enhanced accuracy. BP adds 10% additional weight when available—purely additive, no penalty if not tracked.

Pacemaker support - Specialized mode for pacemaker users that excludes fixed HRV values and intelligently redistributes weight to other cardiovascular metrics.

Pace of aging - Track how fast you're aging relative to chronological time with 12-week comparisons and 24-wee
