1Blocker X

1Blocker allows you to block irritating advertising, trackers, and other features on websites. You're safe online with 1Blocker, and nothing will keep you from enjoying websites. 1Blocker is really simple to use; simply flip a few switches to begin blocking advertising and trackers. The program will discreetly get cloud updates to the built-in filters, so you won't have to do anything. It's as simple as setting it and forgetting about it. 1Blocker is a fully native program designed to naturally enhance Safari. It's small and doesn't deplete your battery by consuming your device's resources. Because Safari handles the blocking, it is really quick. It merely adds filters to Safari and does not alter web pages in any way.

1Blocker is a highly adjustable content blocker that allows you to set strong custom rules. It enables you to design custom rules that can block any URL with a regular expression or hide any element using CSS. It also allows you to disable cookies. (Only available in Premium.) 1Blocker is available for iPhone, iPad, and Mac. Your preferences and custom rules are always in sync through iCloud no matter which device you're using.
