longevity, closed loop

Aging is the target.

amity watches how your biology changes, chooses the next useful test or intervention, then checks whether it changed the trajectory.

why longevity

It is not a general health app.

amity is built around one specific problem: aging. The system tracks biological change over time, uses that history to decide what is worth doing next, and measures again after an intervention.

01

Track drift
See what is changing across time, not just what is out of range today.

02

Intervene deliberately
Choose a test or intervention because it resolves a real uncertainty.

03

Close the loop
Measure again and keep what actually moved the trajectory.

trajectory, not score

Same age.
Different curve.

The goal is not a younger-looking number. It is changing the direction of biological decline.

the product

One decision, then evidence.

amity should tell you what to do next, why that step is worth doing, and when to measure again. The interface is the decision, not the dashboard.

amity is in development. This site describes the intended product direction and focus on longevity. It is not proof that amity can literally stop human aging today, and it is not a substitute for professional medical advice.
