This is the old version. We had to re-release our Mac app because of some App Store constraints to support universal purchases and Family Sharing.

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

We have been making 1Blocker since 2015. We’ve learned a lot from our customers and improved the app consistently for 5 years to suit all your needs. We believe it’s the best all-around package currently available in the App Store.

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!

Well worth paying for

There's a lot of options for content blockers (hey internet! Take a hint!). 1Blocker does what I need and want unobtrusively and allows for fairly easy whitelisting for sites that simply don't work with blocked elements.

I've found 1Blocker to be the most consistent on my phone for some time and just started using in on my Mac as well. The uppgrade prices for premium are fair (I was a user before the switch and was grandfathered into most of the features, but paid again because, you know, the developer has to eat to keep making software) and the option for a ifetime "subscription" is welcome.

There are a few niggling annoyances but they mainly come down to the wide variety of ways that html, css, and javascript can be implemented on any given site. (Most of my annoyancrs have to do with desiring to whitelist sites to support them, but their ads are conflated with their tracking beacons/cookies and look like the worst of Geocities).

I have not run into any sites where whitelisting failed to provide access - which has happened with other content blockers (mainly on educatiion portals).
