01
Prepare iPhone and Apple Watch

- Make sure OneCentrate is installed on the paired iPhone and Apple Watch.
- Open OneCentrate on iPhone and review the iCloud account and device registration.
- Open OneCentrate on Apple Watch, then use the on-screen control or horizontal navigation to choose Switch, ki.log, or Pulse.
The Watch app uses the last state received from iPhone. If it is empty or shows an older state when first opened, open OneCentrate on iPhone, wait for the connection to recover, then check again.
02
Start and control a Switch
Select and start a Switch that is enabled for Apple Watch. While it runs, view the current stage and time, then use Pause, Resume, or End.
The paired iPhone receives a request from Apple Watch, applies it to the actual session, and confirms the new state. A queued indication alone does not mean that starting, pausing, or ending succeeded, so wait for the changed state to appear on Watch or iPhone. If another Switch is already running or the mode's access requirements are not met, the start request is declined and the Watch app can reload the latest state.
To configure the full Switch and its run devices, see Choose run devices on iPhone, iPad, or Mac.
03
Record in ki.log

The ki.log screen shows up to eight high-priority TODAY lists due today and DONE lists that reached today's target. NEXT lists are excluded from the Watch list and rectangular complication rows. Select a list to check it once or add one completion toward its target. After reaching the target, you can reduce it once.
The maximum of eight limits what appears on the Watch screen, not notification reservations. A change sent while disconnected can remain pending and be reconciled when iPhone reconnects. A pending indication alone does not mean recording succeeded, so confirm the actual record on iPhone. See Use ki.log in widgets and on Apple Watch for details.
04
View the current and next Pulse


Pulse shows the current rhythm as NOW, the next rhythm as NEXT, and arranges today's schedule in time order. When no rhythms remain today, it shows DONE.
Select the bell button in today's list to mute or re-enable alerts only for that occurrence of the date and time rule. Create or edit the complete rhythm and change future alerts on iPhone, iPad, or Mac.
05
Review complications and availability

Choose a OneCentrate Switch, ki.log, or Pulse complication for the Watch face. Circular, rectangular, and inline formats provide a brief current Switch state, remaining ki.log list, or next Pulse, and open the corresponding Watch screen.
You cannot create cards or edit detailed settings on Apple Watch. Analysis and OneCentrate AI are also unavailable. Some actions can remain queued while disconnected, but confirm the final result after reconnecting to iPhone.
