There are several options available to block porn-related web content on your iPhone or iPad. Users running iOS 12 have Screen Time to filter adult content, while devices running iOS 11 or earlier have a similar option using restrictions via the general settings area.

To ensure all web browsers (not just Safari) block porn on your iPhone, OpenDNS provides free, pre-configured DNS servers that filter out a vast selection of adult and x-rated content. Mobile apps (free and paid) are another viable solution to block porn websites on your device.

The instructions included in this article apply to devices running iOS 10, 11, and 12.
