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


Send your feedback at @1BlockerApp on Twitter or via email. Your feedback is always very welcome and considered for the next release.

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.

Unique Outstanding Design App!

I have used this unique 5 Star app for many many years! In fact I can remember when the Name change on the App and slowly changed back to the current Name on the App. But I can contend know matter what the Name was the Outstanding App always worked for me it never never did fail me. The Developers have put a great deal of time sweat love and yes Hard Work on the coding of their Software. They surprise me when they added the Firewall protection which has always worked and been a success in a protected system that I as an ole man needed. I have been lucky thru my many years that I got to see Technology change so much and thanks to these Developers that I was going to use some of it! I truly truly appreciate and thank the Developers for all their hard work in keeping up with all the security concerns and corrections that needed to be made on this Software and that they did with all the updates that they did through out the years! So as an ole man I want to Tip my Hat 🎩 to you and say “ Thank’s “ for anyone who read this I Hope you will Download this and give it a try. I Don’t believe you will be disappointed or sorry! I can’t seemingly remember ever being disappointed by this App over the past years I have used it! Thanks

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.......

Great App and Support

I originally got the free version, which allows you to use one component. I chose the Safari Ad Blocker. Worked great, but I was having an issue on one site. Used the contact-the-developer function, and they responded and were able to solve the problem for me. Was so pleased that I decided to give the paid version a try for at least a year, allowing me to add blocking for web trackers; and for in-app trackers (firewall). I don’t notice any slowdowns for the ad blocker. *Maybe* minimal *occasional* delays after enabling the other features. Highly recommend, for greatly enhanced privacy and great support. Also, everything is laid out nicely, and clear descriptions are provided for every element.

(This review replaces a longer, more detailed, review I was just finishing, that went away when I got a second phone call. Didn’t want to restart from scratch.)
