In response to growing calls for technology companies to help people avoid spending too much time on their devices, Apple appears to be stepping up with new time-management features in iOS 12. With new App Limits, you can set limits for the amount of time you spend in specific apps. When the time you’ve allotted yourself in the app is nearly up, you’ll get a reminder that it's time to close out and, you know, enjoy your life. When time is up, a notification will take over the screen. However, you can dismiss this and give yourself an extension if you’d like.
Finally, after years and years of displaying every single one of your notifications -- even multiple notifications from the same app -- as a giant list on your lock screen, Apple announced it will organize your notifications into groups. This is just one of several features to better display your notifications and help you manage them better.
In addition to grouping notifications, iOS 12 allows you to turn off notifications from certain apps or have future notifications from certain apps delivered directly to Notification Center right from your lock screen. Siri can also suggest tweaking these notification settings based on your app usage.
