1Blocker lets you block obtrusive ads, sneaky trackers, and annoying elements on sites. With 1Blocker, you’re safe online and nothing will distract you from enjoying sites.

1Blocker is very easy to use — just flip a couple of switches to start blocking ads and trackers. The app will automatically receive cloud updates to the built-in filters silently, so you don’t need to do anything. It’s as simple as setting and forgetting.

1Blocker is a fully native app designed to extend Safari naturally. It’s lightweight and doesn’t drain your battery by taking up your device’s resources.

The blocking itself is super fast because Safari does it itself. We only provide filters to Safari and don’t modify webpages in any way. This vastly improves efficiency because Safari knows in advance what should be blocked. So, with 1Blocker, sites load on average 2-5x faster.

It’s important to note that not all ads can be blocked though. Some sites use techniques that make it impossible for us to block their ads using currently available features for Safari content blockers.


1Blocker is secure and private. It doesn’t have access to webpages and doesn’t track you in any way.

We believe that privacy is not for sale. That's why we don't have an "Acceptable Ads" program. We stay independent, and the only way we make money is through direct sales of 1Blocker in the App Store to you.


1Blocker is a highly customizable content blocker, providing the possibility to create powerful custom rules. It allows you to create custom rules that block any URL by providing a regular expression or hide any element by CSS. It also lets you block cookies. (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.


1Blocker has been featured in TechCrunch, Lifehacker, MacStories, Macworld, and many more.


• The ability to enable one category (for example, Block Trackers only)
• Whitelisting sites right from the Safari extension
• Whitelist synchronization between devices via iCloud
• The possibility to see blocked resources on a site

Alles top wieder mein Favorit 1

Aber für die Firewall eine Status Anzeige wäre top und automatisches löschen der Firewall Verlauf ! Und ist in der Premium Version um 16€ der beste seiner Klasse ! But a status display for the firewall would be great and automatic deletion of the firewall history! And the premium version is the best in its class for € 16!

Blokt leider nichts mehr ab

Bisher super funktioniert. Seit 3 Tagen wird Werbung auch Youtube nicht mehr blockiert.

Developer Response ,

Thank you for letting us know about this situation.
The problem is that Google introduced a new ad format some time ago, which caused unexpected side-effects while using YouTube with 1Blocker enabled. Apple's tools that we use are a bit limited, and they can't cover certain YouTube scripts right now, that’s why certain kinds of ads may go through until we have a proper solution.

Google puts a lot of effort into making YouTube's ads invisible for content blockers. And they usually roll out the changes for specific groups of users only, making it really challenging to reproduce them.
Many content blockers are affected by these changes, but we keep monitoring the situation, and it may become better with each update.

Really good but…

… drains battery very quickly. I think you should work on that.
Otherwise, really very good.

Hello GerBre0815,
Thank you for your feedback. Happy to hear that you like our app!
I agree that it should be worked on, and we are looking for possible ways of optimising the app and improving its impact on the battery life. Please, stay tuned for future updates!
The only way to fix it for the moment is to disable the Firewall's toggle. Content Blocking in Safari will still be working as usual without affecting the battery life.
