In window mode, an alert time is selected randomly within your chosen window, with your set alarm time serving as the latest wake-up time. This mode does not use sleep stage detection. When a fixed-time alarm sounds, you can also snooze for 5 minutes. Sync your next alarm time with your paired iPhone. Alarms must be enabled separately on your iPhone and Apple Watch. Stopping or snoozing an alarm affects only the device you are using. Syncing alarm times does not change alarms that are already enabled.
