WELLNESS, MEASURED PRIVATELY

Prime turns the Apple Health signals you choose into a private wellness estimate, then shows what moved and whether your trend is holding.

01

One score

Prime condenses available signals into a clear wellness estimate and shows confidence when data is thin or missing.

02

Three drivers

Recovery, Strain, and Capacity explain which current signals are supporting your estimate and which are pulling against it.

03

Your trend

Aging Pace and weekly history make recent direction visible without turning your health into another advice feed.

PRIVATE BY DESIGN

Your health data stays on your iPhone

Prime is local-first. It reads only the Apple Health categories you authorize, calculates your result on-device, and keeps score history locally. Prime version 1.0 has no account system, advertising, analytics, or health-data backend.

GOOD TO KNOW

Everything important, before you install.

Is Prime Age a medical or biological-age test?

No. Prime Age is a personal wellness estimate built from the Apple Health signals you authorize. It is not medical advice, a diagnosis, a disease prediction, or a clinically validated biological-age measurement.

Which Apple Health signals can Prime use?

Depending on what is available and what you authorize, Prime can use signals such as sleep, workouts, steps, cardio fitness, heart rate, heart-rate variability, respiratory rate, physical effort, mobility, weight, and lean body mass.

Does Prime upload or sell health data?

No. Version 1.0 processes authorized health information on your iPhone. Prime has no health-data backend, advertising, tracking, or data-broker integration.

What happens when a signal is missing?

Missing or stale signals lower the displayed confidence. They do not count against your score, and Prime shows when information is unavailable.

When will Prime be available?

Prime is preparing for its first free iPhone release. The website will link to the App Store when the public product page is available.
