HOW TO Get started with Screen Time
1 Enable Screen Time
Open System Preferences and click Screen Time > Options > Turn On. To see data from your other devices on the same Apple ID, click “Share across devices”. On iOS, activate in Settings.
2 App Usage
At the top of the sidebar, the App Usage section shows how much time you have spent in each app (or category of app) across the day. You can filter this by device if you have enabled Screen Time on your devices.
3 Notifications…
Below this are the Notifications and Pickups sections. These detail the apps most responsible for disturbing you with notifications, and what apps you first use after opening your Mac or unlocking your other devices.
