What's New in 1Blocker

6.7

October 7, 2026

This update brings a major upgrade to 1Blocker’s filtering engine. Advanced rules, including scriptlets and extended CSS, now work in every filter package, not just YouTube, with support for many more scriptlet types. The result is improved blocking of adverts, anti-ad-blocking messages and pop-ups across many more websites. Make sure the 1Blocker Scripts extension is enabled in Safari and allowed on all websites to get the most out of it. YouTube ad blocking now updates alongside the rest of your filters. For Premium users, external filter lists can now include advanced rules too, with a new “Trust This List” option for scriptlets that require additional permissions. 1Blocker is also ready for iPhone Duo. This version includes several stability improvements and crash fixes. Questions or feedback? Contact us at support@1blocker.com or @1BlockerApp on X. Your feedback helps us keep making 1Blocker better.

Stop looking and get this !

Specifically designed for Safari, this is the best content blocker in the App Store. Just enable the blocking modules and enjoy the internet again. Whitelist websites and create custom rules without having to be a technical expert. Block trackers and data collection by simply clicking on a switch. Receive weekly automatic updates or just open the app to immediately receive the most recent updates
I’ve been a long time Premium member and have this installed on my iPhone, iPad A17 Pro, and MacBook Pro.
So much blocking power and so easy to customize, it makes the other content blockers look like toys.

The Best

I’ve tried a number of blocking apps and this has been the best for years.

Going on 5+ years now

Still kicks major ad butt - thank you devs - wish I could gift this app to friends. Highly recommended

Worse than free alternatives

$15 a year or just use uBlock Origin Lite which is better anyway. 1Blocker used to be heavily recommended online, long ago, then pulled their paid app and replaced it with this freemium one and its subscription. In that time, uBlock Origin finally arrived on iOS, and it’s still made for maximum efficiency with no greed.

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.
