Apple Watch
Its own token, so the phone can stay in the locker
SUITA on Apple Watch is not a phone relay. It talks to the server itself, runs the session from your wrist, and keeps the day honest about what it can and cannot record.
Paired once, then out of your way
Pairing is the only part of the watch you ever have to think about, and there are two routes through it.
Its own token
The watch talks to the server itself rather than relaying through the phone, so it keeps working while the phone sits in a locker.
Ninety days, sliding
A paired watch holds a token with a ninety-day sliding life, so a watch you use stays paired and one you put in a drawer does not stay paired forever.
Two ways to pair
The phone hands a token over the private channel, or the phone shows a short-lived pair code that the wrist dials. Either one gets you running in a minute.
One live pairing at a time
A live pairing is only ever replaced deliberately, and that replacement is the cut-off for a watch that was lost or handed on. Revoking a watch is never behind the paywall.
On the wrist, the day is already there
- The dayWhat is planned, in the order it happens
- MacrosMoving with every meal you tick off
- WaterGlasses counted against your target
- The next mealWhat it is and when it is due
- The burnWhat the day has cost you so far
It runs the session, it does not just report on it
The work happens on the wrist, where your hands are. The phone is for the parts that need a screen, and nothing waits on it.
- Exercise loops, so you can see the movement before you do it
- Set and rest timers through the session
- Heart rate across the work, with the zones reaching the coach
- A nudge to photograph the meal while it is still in front of you
A tap that lands, or a reason it did not
It refuses with a reason
When the watch clock is too far off, it says so and stops, rather than showing a day where no tap you make will ever land.
Every tap names its day
Taps are idempotent and each one carries the day it was made on, so a queue flushed after midnight still files against the right day.
The coach sees the work
Heart rate zones from the session reach the coach, so what it says next is grounded in the session you actually did.
