Screen Time can set daily limits for categories or individual apps. When the allowance runs out, the iPhone can block the app unless more time is approved.
- Open Settings > Screen Time and turn on Screen Time if it is not already enabled.
- Tap App Limits.
- Tap Add Limit and select a category or expand a category to choose particular apps.
- Tap Next and set the daily amount of time.
- Turn on Block at End of Limit if you want the limit enforced, then tap Add.
For stronger limits, use a Screen Time passcode that is different from the device passcode. Screen Time also includes Downtime and communication/content controls. Limits for a child’s device can be managed through Family Sharing when the family setup supports it.
