Block trigger apps.
Enable adult-site protection.
The current iPhone release uses Screen Time to shield selected apps. App blocking requires iOS 16 or later. Enable the requested access in Nafs, then choose the apps you want to restrict.
Nafs also enables Apple’s adult-content filter for Safari and in-app WebKit on iOS 16 or later with the required Screen Time access. Coverage depends on your device and browser. Check protection on your phone, and use Apple’s web restrictions or another layer for uncovered routes.
