Mira
See how fast your body is actually aging
How old is your body actually behaving? Mira reads your HealthKit data (sleep, HRV, heart rate, steps) and gives you one number back: your biological age. Every Monday, a fresh reveal. Sometimes younger than your birthday. Sometimes older. Either way, you finally know. Mira's insight engine, reads your personal patterns and tells you what's moving your number. Specific to you. Not generic advice. Free to try on iOS. Premium for deeper insights. Stays on your phone.
Apple Health has years of my data. Sleep, HRV, resting heart rate, steps, all sitting there. But opening the Health app is like opening a spreadsheet. Graphs, numbers, trends, no meaning. You scroll through it and come away with exactly zero insight. The data is there. It's just unreadable in any useful way.
Biological age apps exist, I tried a few. The math is usually fine. The experience is not. Most of them feel like calculators: data-dense, clinical, nothing you'd want to come back to. Meanwhile the design bar set by fitness brands like Bevel and Whoop keeps going up, and bio-age tools haven't caught up.
So I built Mira with two obsessions:
Interpret the data, don't just display it. Mira's insight engine reads your personal patterns and tells you what's actually moving your number. Not "sleep more." Specific: "Your HRV drops on nights you sleep under 6 hours." Your data, your patterns, your insight.
A weekly reveal ritual instead of a dashboard you stare at every day. Something that belongs on the home screen next to the apps you actually like opening.
Is biological age a precise measurement? Yes, and also no. The concept is well-studied (Levine's PhenoAge 2018, Horvath's epigenetic clock 2013). Blood biomarker tests are the gold standard. Your Apple Watch sensors are a useful approximation.
Three things that mattered to me while building it:
Your HealthKit data never leaves your phone. Not to me, not to a server, not anywhere.
No account needed to start. Download, grant HealthKit permission, see your number.
Free to try. Premium is there if you want deeper insights, but the core experience works without paying.
If you try it and the number surprises you, tell me below. Reactions so far have ranged from "yeah that tracks" to "wait I'm eight years younger than I thought" to "I need to fix my sleep immediately." All valid. That's kind of the point.
If it clicks with you, an App Store review helps more than anything. Thanks for reading this far.
