Own your prime.
Two numbers, both earned. Prime is your fitness — it climbs over weeks. Readiness is today's live market — how ready you are, right now. Built from the health data your iPhone and Watch already collect.
Both numbers, without the ring.
Rings and straps charge three hundred dollars — then a subscription — to measure what's already on your wrist. Prime reads it straight from Apple Health. The same handful of signals feed both numbers: the slow one you build, and the live one you spend.
Your capital, and today's market.
Most apps blend everything into one score. Prime keeps them honest and apart — because getting fitter and feeling ready are two different things. Think portfolio and ticker.
Your numbers, explained in plain words.
Prime doesn't just show you a number — it tells you why. What's holding your Prime back, the one habit that moves it most, how to read today's Readiness. Written in plain language the moment you open the app, and generated entirely on your iPhone by Apple's Foundation Models. Your health data is the prompt — and it never leaves the device.
Watch your training move the number.
Every session lands in the app. A hard effort spends Readiness — you watch the dip, then the recovery that follows. Show up week after week and your Prime climbs. Strain is what you spend; consistency is what you build.
See the Prime you're building.
Readiness you live; Prime you build toward. Set a target for your Prime — the app prices every habit in points and shows the eight-week climb, like an amortization table for your body.
Both numbers, at a glance.
Your morning briefing lands on the wrist. A live Readiness ticker moves through the day as you train and recover — like a market on your arm. Complications keep your Prime and today's state one glance away, all day.
