About
Mira is a bio-age instrument for your Apple Health data.
It watches quietly all week, then reveals one reading every Monday morning: your biological age, how it moved, and the two or three signals that drove it.
No daily scores. No streaks. No pressure to optimize. Just a calm, weekly read on your body.
WHAT MIRA TRACKS
Sleep duration and consistency, heart-rate variability, resting heart rate, VO2 max, steps, active days, strength minutes, cardio minutes, and heart-rate zones. All pulled straight from Apple Health.
THE WEEKLY REVEAL
Every Monday at 10 AM, Mira shows you:
• Your biological age for the week
• Delta vs. your actual age (younger, on par, or older)
• The metrics that moved it, explained in plain language
• A 6-month trend so you can see the shape of the change
PER-METRIC DETAIL
Tap any metric to open its story:
• 7, 30, or 90 day trend with your target line
• How you compare to the top 10% and the cohort average
• What Mira sees in the pattern, grounded in your own data
PRIVATE BY DESIGN
Mira reads Apple Health on-device. Your health data never leaves your phone.
BUILT FOR THE LONG READ
Mira isn't a daily tracker. It's an instrument for people who want a quiet, honest signal on their aging. Once a week, every week.
Apple Watch or iPhone required for Apple Health data capture. Mira works best with at least one month of history.
