Wear OS 2.0 removed synchronization of the Do Not Disturb state between the watch and the phone. This application restores the old Wear 1.5 behaviour.

Version 1.4 of the application registers a minimal listener service to get notified of Do Not Disturb state changes.

Follow the steps below to activate watch to phone syncing:

1. Install and launch the phone app.
2. Tap the "Grant Permission" button and grant the app the requested permission.
3. Install and launch the watch application from the Play Store.

Version 1.1 of the app optionally adds support for bi-directional sync for users able to use ADB. To enable phone to watch sync, users need to manually following the steps described at the link below.
