Recent loss of function

As of July 24, 2026 it has stopped working. Ads all over safari. Had no problems for years of use till now. Needs an update. Then, 5 stars.

Does not work

This does not block any more ads than the standard safari settings. On Fandom websites, it blocks nothing so it’s pretty much useless.

FAQ

What does 1Blocker do?

1Blocker enhances your browsing in Safari by blocking intrusive ads, sneaky trackers, and annoying website elements. It aims to provide a safer, more private, and distraction-free online experience, often resulting in significantly faster website load times.

What are the key features of 1Blocker?

Key features include blocking ads and trackers, improving website load speeds, ensuring secure and private browsing, offering advanced customization for blocking rules and hiding elements, and allowing users to whitelist specific sites. Preferences and custom rules can sync across devices via iCloud.

Is 1Blocker free to use?

The app offers a free version that allows users to enable one category of blocking (e.g., Block Ads only), whitelist sites directly from the Safari extension, and synchronize whitelists across devices. Advanced customization features, such as creating custom rules for blocking URLs or hiding elements via CSS, are available in the Premium version.

What devices is 1Blocker compatible with?

1Blocker is available for iPhone, iPad, and Mac. User preferences and custom rules are kept in sync across all these devices through iCloud, ensuring a consistent experience regardless of the device you are using.

How does 1Blocker improve website loading speed?

By acting as a Safari content blocker, 1Blocker provides Safari with filters in advance, allowing the browser itself to determine what should be blocked. This native integration is highly efficient, as Safari knows what to block before loading the page, leading to websites loading on average 2-5 times faster.
