Timer Sync keeps the current timer and session settings in sync on devices that use the same iCloud account. That includes durations, cycle, and auto-start.
It is available on iPhone, iPad, and Mac. It is not available on Apple Watch or Apple Vision Pro. It requires Flow Pro.
Turn it on in Settings.
Statistics
Section titled “Statistics”Session statistics sync through iCloud on their own. You do not need Timer Sync for that.
If sync is not working
Section titled “If sync is not working”- Sign in with the same Apple ID on each device (Settings → Apple ID).
- Enable iCloud for Flow on each device (Settings → Apple ID → iCloud).
- Confirm each device is online.
- Compare the Sync Key in Timer Sync details on each device. If they differ, restart Flow and turn Timer Sync on again on every device.
Some regions may not have full access to the cloud service Flow uses. In that case Timer Sync might not work correctly.
