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 see 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 see 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.

The best blocker on IOS

It’s a one off purchase not an annoying subscription like most apps are trying for these days. For less than 2 beers you get the best blocker out there.

I found it frustrating that the older version is no longer rated 5 stars because people are moaning that they upgraded that app only for this new one to come out and calling the dev greedy. That app was over two and a half years old and we seem to live in a world where people want everything for free and forgot that the dev needs to earn an living.

So in short if you want the best app for blocking the ever increasing rubbish on the net and are not deluded to think that quality is free get this app.

Once great, but categories let it down

This was once one of the best blockers on the market. However, changes to the category groupings have made it unusable. Previously (and still on the desktop version), EU cookie notices, crypto-miners, and other annoyances were in separate categories.

Now they are grouped together under “Annoyances”. The problem with this is that some sites are broken by blocking EU Cookie notices, as it’s a legal requirement. A site breaking because you blocked a crypto miner is fine (that probably isn’t a site you want to use anyway), but almost all sites have cookie notices. Before you could turn off blocking for those categories independently, now you either have to deal with cryptominers and such as well, or have lots of site break.

If they bring back granular categories then it would be 5 stars, as the basic ad-blocking is great. But 1Blocker X is sold and priced as much more than an ad-blocker and design changes have made those features broken.

Hello, James!
We really appreciate your feedback, your review is very helpful. We just wanted to let you know that we will consider returning EU Cookie notice section back. Please, stay tuned!

Excellent blocker that just works

I’ve tried several paid ad blockers since moving to iOS. Some of them have partially worked, others have barely worked. At one point I was using more than one app but the combination still wasn’t satisfactory. None of the apps I tried blocked EU cookie notices, many of which are an intrusive annoyance.

This app blocks the lot and has a very fine-grained degree of control, also an excellent whitelist ability that allows you to fully or partially whitelist domains.

I also found the developer to be very helpful when I had an inquiry. An essential app 👍
