Biological age is the long view of everything else the ring measures — sleep, recovery, heart, movement — expressed as a number you can move. Not a prophecy. A direction, checked every month.
Your cardiovascular pillar improved through the spring, alongside more zone 2 minutes.

Chronological age rises at exactly one year per year. The other line is the one worth watching — and a month where it flattens instead of falling is still a month you spent well.
Resting heart rate, HRV and rhythm over months rather than mornings.
Moves with: zone 2 minutes, alcohol, sleep regularityHow reliably you return to your own baseline after load.
Moves with: sleep debt, training balance, stressOvernight temperature and heart-rate behaviour, plus what your notes say about late meals.
Moves with: meal timing, late sugar, movement after eatingREM and deep sleep consistency, the parts of the night most tied to thinking.
Moves with: bedtime consistency, caffeine cut-offTemperature rhythm across weeks — and across cycles, if you track them.
Moves with: sleep timing, cycle phase, illnessTravel, time zones, altitude, noise and the nights they cost you.
Moves with: flights, late light, unfamiliar bedsEach pillar borrows its colour from the Circle it draws on, so a pillar and its source data look related wherever you meet them.
Longevity does not ask for another test or another wearable. It is the long-window view of the signals the ring already takes every night, which is also why it needs a few months before it says much.
Your resting heart rate fell 4 bpm across ten weeks, alongside a rise in zone 2 minutes. The pillar moved with it.
Overnight temperature runs high on days with late meals — 14 of your last 20 tagged late dinners.
REM consistency tracks how regular your bedtime is more closely than how long you sleep.
Across six trips, your environmental pillar dipped for three nights and recovered by the fourth.
No streaks to lose and no badge for a perfect year. Milestones stay available until you reach them.
It is a model, built from what a ring can see. It is not a blood test, not an epigenetic clock, and not a life expectancy. Its value is that it moves when your habits move — and that it does so slowly enough to be believable.
Around three months. Longevity works on a 90-day window, and the app shows how much of it you have filled rather than producing an early guess.
Slowly, by design. A good week does not move it; a changed habit held for two months does. Anything that swung daily would not be measuring ageing.
No. Those use a blood or saliva sample and measure something different. This is a physiological model built from continuous wearable data.
The app names the pillar responsible and what moved with it. Illness, a hard training block or a month of travel all show up here — and all of them recover.
Yes. Longevity is a Circle like any other and can be removed from your home screen entirely.
No. Biological age, the six pillars, detected patterns and milestones are included with the ring, permanently.
