Which device takes priority?
Any notifications will come to your iPhone if it is unlocked.
And to your watch if your iPhone is locked or in sleep mode
You may not see notifications on your Apple Watch if your watch and iPhone have become disconnected.
Take control of your notifications
By default, your Apple Watch notifications are set up to mirror your iPhone settings. For example, if you set your iPhone Mail app to notify you only of VIP emails and your watch notifications mirror your iPhone, you’ll see only VIP email notifications on your Apple Watch.
You can change how you are notified on any built-in app by:
- Open the Apple Watch app on your iPhone, then tap the My Watch tab.
- Tap Notifications, then tap an app.
- If you want the app’s notification settings to mirror settings on your iPhone, tap Mirror my iPhone. If you want to use different notification settings just for your Apple Watch, tap Custom.
For third-party apps, you can turn off notifications. Scroll down to the Mirror iPhone Alerts From section and turn off the setting next to the app.
