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 4.0

1Blocker 4.0 for Mac adds a new Web Extension that can block ads on YouTube.

The new Web Extension is optional, has no interface, and its purpose is to perform more advanced content blocking that the original Content Blocker API doesn't provide.

Currently, the extension can remove ads on YouTube. But we'll expand its functionality in the future.

You can activate the extension in Safari preferences → Extensions → 1Blocker Scripts. Make sure to give access to all sites (or at least to

Update: Working Great Now

Update: so there seems to be a gap between settings inside the 1Blocker app and the whitelisting section of the extension inside safari. I discovered today that even though I had removed the whitelisting rules inside the safari extension, those rules were being overridden by a whitelisting setting in the app itself. After removing the toggles inside the app, the blocking resumed as expected. However, the whitelisting settings remained inside the extension. Regardless, I’m satisfied that things are operating as expected. Good work!

Sites like Forbes are not cooperating at al. With all blockers turned on and given permissions, Forbes just runs wild with huge banners and pop ups. It’s not the only one. I have never had issues until the last few weeks or so. I got a link from my grandma for an article there and when it loaded I assumed none of the blockers were on or maybe I had it whitelisted and I did have it whitelisted. I turned that off, let Safari process the rules, and reloaded the page. Still no go

Works perfect

Many OTHER ad blockers have fallen into disrepair, not having been updated in ages or at least visibly updated and losing their effectiveness. This one bucks the trend and goes full throttle ad blocking with great configurability such as easy white listing. I only wish that some websites that I visit and enjoy had ads that weren’t so utterly obnoxious that they hijack my Safari with a new page to announce “You’ve own a prize! Click OK!” And then I can’t find my way back because swiping back just loads the ad again. UGH. Well, this blocker effectively stops that crud with the latest policies. I’m sure it is a full time job just keeping that up to date so the app cost is perfectly reasonable. Technically the app is above all the rest since they’ve managed to implement more than 50,000 policies using a modular system. Awesome. Now if only websites realized their ads were so obnoxious that JUST MAYBE less obnoxious ads would result in less ad blocking and more revenue.......

This is the app I will continuously keep leaving a good review for because it is THAT incredible. I bought the lifetime subscription and couldn’t be happier! The developer (or developers?) does an incredible job and is always responsive to any help or support I need.

First thing I want to say is to all the people emailing in for support, please be nice because I can tell these people get a LOT of support requests every day and they don’t necessarily develop an app just to answer emails all day. They made the app to block content in safari and now block trackers system wide with the firewall :). Adding email support on top of that is really hard and you have to respect the crazy amount of work this developer does.

To the people who make this, thank you so so so much for the incredible app. It feels like something apple themselves would make and it’s truly the polished content blocker experience I was looking for !!!
