1Blocker is the fastest and most powerful Safari content blocker that improves your browsing experience by blocking ads, trackers, and other unwanted content, such as popups, cookie notices, comments, and more.

1Blocker is secure by design — we don't track the sites you visit. We protect you from online tracking, data collectors, and help you be focused on important things. We think that 1Blocker is an essential app for anyone who uses Safari.

An independent team of two app developers is working on 1Blocker. Our mission is to make the Internet a better and safer place for as many iOS and Mac users as possible.


Blocking unwanted content with 1Blocker is extremely fast and doesn't slow down Safari.

We use Apple's native tools to tell Safari in advance what should be blocked. This vastly improves efficiency, reduces data loaded, and saves battery life.

1Blocker makes sites load on average 2-5x faster.


We don't have access to webpages and don't track the sites you visit. That's because Safari itself handles all blocking, we just provide rules for it.


1Blocker rules automatically stay up-to-date thanks to our powerful cloud service that builds and sends you new rules twice a week. (Available in Premium)


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 on the App Store to you.


1Blocker is a highly customizable content blocker, providing the possibility of creating 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 works seamlessly on all your iOS, macOS and iPadOS devices. Your preferences and custom rules are always in sync no matter which device you're using.


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

What’s New

Version 3.1

1Blocker version 3.1 brings various small improvements, adds Click Mode to the Visual Editor, and includes an updated set of rules.

When you use our Visual Editor to hide a webpage element in Safari, you can now temporarily disable selection by activating Click Mode, which lets you perform click actions. For example, you can activate Click Mode to log in to your account, navigate to a different page or open a menu before selecting elements to hide.

In the next updates, we will focus on interface performance improvements. I thank you for being patient.

If something’s not working right, you have an idea you’d like to share, or you just want to say hello, contact us anytime at @1BlockerApp on Twitter or via email. Your feedback is always very welcome and considered for the next release!

If you enjoy using 1Blocker, please leave a nice review here on the App Store. We read everything and it means a world to us. Thank you!

Wonderful Payment options for upgrading users

I bought 1Blocker Legacy (1.0) on both iOS and Mac a few years ago. I held off on switching to 1Blocker X because it came out just a few months after I paid for the first version.

The free upgrade from 1.0 to 1Blocker 3.0 (this version) is incredibly generous! I also appreciate the fact that there is a 1 year trial of the cloud features. I'll be purchasing the lifetime version of 1Blocker 3 to further support the developer :)

Note to dev: I had 1Blocker legacy installed on my Mac and iPhone. I first tried downloading 1Blocker 3.0 on iOS, and the pricing options did NOT take my previous purchase into account (ie. full price and no 1 year trial offered on my phone.. both Legacy and 3.0 were installed at the same time). However, the Mac version installed as an update over top of the legacy Mac app, and then the pricing adjusted on both iOS and Mac (over iCloud I guess). Just a note that some people might be confused by the experience on iOS (I noticed some reviews in the iOS App Store indicating similar experiences!)

Best ad blocker, great value

1Blocker is by far the best content blocker on iOS, and so far seems to be the best on macOS. It's fast, easy to use, well-designed, and—most importantly—effective.
Everything from ads to social media buttons to trackers are just gone, with no trace of them left behind. I've noticed other blockers for the Mac block the ads but leave a huge white space where they used to be...but not 1Blocker.
As far as cost goes, the app is incredibly reasonable. I bought the iOS version years ago, and would have been happy to buy the macOS version as well. But you don't even need to because the developer makes essentially the entire app available for free. The "premium" subscription gets you more frequent updates, but for a measly $4.99/year I subscribed just to support the developer. Great job!

Much Improved, Cloud Rule Synch, Super Developer!

1Blocker for MacOS and iOS: Well polished and robust content blockers.

UI: Nice, clean, and pleasant to use. Nice text, nice icons...A big improvement from the last version.

Blocking: In my testing blocking is very effective and fast as well. With the ability to create custom rules and have them synch to all your devices is a huge bonus feature. And now with the ability to unlock premium and have weekly cloud rule updates, I could not ask for anything more.

Bonus: Very responsive and helpful developers. I had annoying issues with a site that was above my experience as far as creating complex rules. Shortly after reaching out, the devs posted their own custom fix just for me. That is rare these days and I really appreciate it.

Go ahead and purchase a subscription or the discounted lifetime option as I did. You will not regret it.

I am very pleased with all these new improvements
