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-week rolling averages. Full-fidelity charts - Beautiful, scrollable charts for VO₂max, HRV (SDNN), Resting HR, Walking HR, Sleep, Recovery Capacity, and more straight from Apple Health. Privacy-maximal - All data and AI processing stays on your device. Zero servers, zero cloud storage, zero analytics. Your health conversations never leave your iPhone. You control everything.

Make it faster and also maybe remind to take blood pressure or other missing data if that was recorded before but not taken in a while. **Developer response:** Will look at improving the scrolling and reminders for BP is coming very soon ### 4/5 — Does what it says, but… *2026-05-19* I was looking for an app that would approximate my biological age à la Whoop, without the price tag, and this app does just that. It seems like the team is just a solo dev, so thanks for developing a good app and releasing it for free. My only gripe is that I wish I could interact with the AI. The templates are a good starting point, but I wish I could ask my own follow up questions. If I’m chewing up my memory to store the AI, I want to be able to use it more fully! ### 2/5 — Incorrect *2026-04-21* Sleep data is incorrect making the rest of the data incorrect. **Developer response:** Fix incoming in a few days, thanks for the patience here. ### 3/5 — Sleep data not syncing *2026-04-10* Apple Watch sleep data is not syncing correctly with bio age….apple data averages 7.5 hours / night for pay 6 months. Bio age average is 5 hours. Is that low number affecting my bio age?? **Developer response:** Fix incoming in a few days, thanks for your patience here. ### 3/5 — Very promising app *2026-03-06* At the time of this review, this is a brand new app. I found it by accident, and really like it. It is simple, and does what it says. The age does not seem to be dramatically optimistic like some other more commercial apps I’ve tried. (I was actually a little depressed when I first got my number, because I guess I’ve been used to the “you look so much younger than your age“ apps. The app is new and has some growing pains for me. It repeatedly shows my age to be around 35 (i’m in my 50s) on the Apple Watch version, unless I actually have the Phone app open, in which case it will correct to my real number for a while, and then eventually revert back to 35. The recent app update says this has been fixed, but it is still a problem for me. Also, when I installed both AI engines my phone crashed repeatedly when using the app, even though I have over 100 GB of free space (on an iPhone 16). When I deleted the bigger more advanced AI model this problem went away. Anyway, these are problems of an early app, which I’m sure will resolve. This is a great app that I’m very glad is being developed. UPDATE: two months later, and I’m deleting this app. No meaningful improvements in two months, and doesn’t seem to provide much meaningful, actionable information that I can trust. Maybe I’ll download it again in a year or two and see if it’s something more useful. ### 5/5 — Clear & simple interface for free *2026-02-02* Excellent app, no excessive input, just a quick sync to your existing health data and you get everything ### 4/5 — Very promising app *2026-01-12* At the time of this review, this is a brand new app. I found it by accident, and really like it.
