HOW TO Set limits on apps
1 Choose a category
Click on App Limits and on the “+” button to create a new limit. This is category–based, and if you’ve created a new Apple ID for your child, the Daily Average column and categories will currently be empty.
2 Add the limit
Pick the category you’d like to limit screen time for, set the limit, and Apple will automatically apply those limits to any new apps in that category (and any existing ones if you’re using an existing Apple ID).
3 Add more limits
App Limits are really flexible, and you can have different limits for different kinds of apps — so for example you might have a one hour daily limit for games, but allow longer for educational apps or chat apps.
