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.
