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

What’s New

Version 3.10.1

We made 1Blocker's toolbar button less distracting in the new Safari 14. It's more subtle in monochrome now instead of bright blue (your system's accent color). We also optimized the popover, so it should open a bit faster.

We improved the readability of our error codes. It makes debugging easier now when something goes wrong.

We also updated our built-in filters with the latest fixes for sites.

Please send us your questions and feedback at or @1BlockerApp on Twitter. Your feedback is always very welcome and considered for the next release. We'll also help you if there's an issue with the app on your device.

If you're feeling generous with your time, you can support us by leaving a nice review in the App Store. We'd also appreciate it if you recommend 1Blocker to someone. As an independent developer, it means the world to us. Thank you!

A powerful app

I've been using the app for some time and found it useful to keep adverts out of my browsing experience. The latest update seems to be easier to get the settings right for individual websites.

I am happy to take out a subscription since it isn't expensive and helps keep the developer in business.

The developer was quick to respond to my comments about the upgrade to the latest version that seemed to be blocked. The developer listens to and responds to users comments.

Not the review I wanted to write

I bought 1Blocker over a year ago and was absolutely over the moon with it. It provided exactly the features I wanted, blocked ads far more efficiently than any other tool I had used before and was excellently priced for such good tool.

I can't say I was particularly impressed with the update informing me that I now needed to subscribe. While I usually have a passionate hatred for subscription model software, I honestly would have been open to beginning a subscription at the $4.99 tier to support the developer. Unfortunately, this new gimped version of the app does not inspire me to do so. Rule blocking has become spottier, more and more false positives are breaking popular sites and the HTML Element tool — the key selling point for this app — has been removed with a cheery message that it might come back some day. Oh and editing rules in the main app no longer repopulates Safari rules correctly, even with a restart of the browser. Not exactly confidence-inspiring, and certainly isn't going to get me to vote with my wallet.

I understand this is a massive developmental overhaul for this tool, and I can already see the intended direction with the UI changes and constantly updating cloud rules; all positives. But removing features for the end user while simultaneously asking them to fork out more cash is not going to do you, or your review scores, any favours.

Hello, we’re sad to hear that this update didn't bring the experience we intended to deliver. This is the first iteration of the development cycle and we will strive to improve the app in the upcoming releases. Right now we are working on the new implementation of the Hide Element mode which we bring back within the next few days.

Also, we have special conditions for our longtime customers like you. If you already paid for any 1Blocker apps in the past, you can get the current version on all platforms for free forever. All the features you had will be free for you. In case the new 1Blocker doesn't recognize you, please contact us at anytime. We will be happy to get your app back on track!

Update: the "Hide Element" mode is back and waiting for you in 1Blocker 3.0.3, already available on the App Store!

A superb antidote to poorly designed websites

So many websites today suffer from ad diarrhoea: too many ads on web pages. 3 ads are tolorable, but 5, 7, 12 per page is outrageous. So if you're on a slow or even average speed Internet connection, you can be waiting too long for web pages to load. 1Blocker solves those problems beautifully. Well designed, unobtrusive, and flexible. Now we can choose who to support. Much appreciated - thank you.
