The Parental Controls are also known as Restrictions on your iPhone, allowing you to manage which apps, features, and content can and cannot be accessed on your iPhone. In other words, Restrictions give you the power to choose the apps other people can access or cannot access using your device. This feature also lets you set the Screen Time for particular apps.

Step 1: Open Settings on your Home Screen and touch on Screen Time
Step 2: Click on Set up as Parent. There will be an App Limits interface.
