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.
SECURE BY DESIGN
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.
ADVANCED CUSTOMIZATION
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)
AVAILABLE ON ALL DEVICES
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.
FEATURED IN THE PRESS
1Blocker has been featured in TechCrunch, Lifehacker, MacStories, Macworld, and many more.
FEATURES AVAILABLE FOR FREE
• The ability to enable one category (for example, Block Ads only)
• Whitelisting sites right from the Safari extension
• Whitelist synchronization between devices via iCloud
FRIENDLY SUPPORT
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 believe it’s the best all-around package currently available in the App Store.

There’s some underlying profile that sticks around even after deleting the app that I can’t figure out that’s keeping product preview pages from functioning, breaks normal redirects, and completely blocks AI overviews as well. Not everyone wants that but sometimes it’s convenient.
Lots of normal functions are broken though and I can’t figure out where to disable the blocker functions breaking them.
Honestly, devs please help

Can’t block a lot of sites they say they do. Difficult to determine blocked or not tabs don’t show status.
Worked great for years. However, recently it’s been causing issues requiring a complete uninstall and reinstall to resolve. Most commonly, apps will detect “no network connection” or similar. The ad filtering widget will also completely break, and the app itself becomes unlaunchable. The only fix is to delete and redownload.
What more can I say? It’s a terrific app which works perfectly.
Does a good job
Es el mejor bloqueador que he tenido funciona perfectamente lo uso en mi iPhone y iPad no se como sabía de este bloqueador antes 😎
Works perfectly
The ad blocker works. But at the custom rules, it wasn’t enabled so I did every single step to turn it on, and I went back to the app and it didn’t work. I tried to do it again, but still didn’t work.
Just wanted to say that everyone should care about where there personal

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! “ Thank You ! “ 🎩
As of July 24, 2026 it has stopped working. Ads all over safari. Had no problems for years of use till now. Needs an update. Then, 5 stars.
This does not block any more ads than the standard safari settings. On Fandom websites, it blocks nothing so it’s pretty much useless.
Doesn’t block ads on YouTube and YouTube music anymore
