1Blocker - Block ads, tracking scripts, anything

By Salavat Khanov

Open iTunes to buy and download apps.


Block ads, trackers, and any annoying web content. Based on new lightning fast native Content Blocking API, it doesn’t slow down Safari and can't know which websites you visit. We are supported entirely by our users, there’s no “acceptable ads” program.


1Blocker is the fastest & most powerful Safari content blocker. With over 40 000 preinstalled blockers, it's highly configurable.

• Save battery life, bandwidth, and data by over 50% (confirmed by multiple independent tests).
• Whitelist websites you love with our Safari extension.
• All your blocking preferences are automatically synced over iCloud.
• Create your own custom blocker rules (hide page elements, block sites, and cookies).


1Blocker is a leading content blocker for iOS and macOS. It has been featured in The New York Times, TechCrunch, LifeHacker, and many more. What our customers say:

• “Must have app for all iOS users.” — linzycumbia
• “Does exactly what you want it to do, and the customer support is fantastic. Highly recommended.” — Blocky McBlockerson
• “Since Sep 2015, I've tested *at least* 15 content blockers (iPad and iPhone). In my opinion, 1Blocker is the most effective, customizable, and feature-rich iOS Content Blocker in the App Store.” — reedrobertson


While most other extensions block content by filtering elements of already downloaded page, 1Blocker uses modern WebKit blocking technology to tell Safari in advance what should be blocked. This vastly improves efficiency and saves battery life.


1Blocker is not a VPN or proxy server, it can't see what web pages you visit and doesn't expose your privacy.

We are fully supported by our users — we don't make deals with advertisers or sell your data to publishers.


The free version of 1Blocker allows one group of blockers (e.g. "Block Ads" or "Block Trackers") to be used at the same time. So if you just want to block ads, you can do that without upgrading to Pro. To be able to activate multiple packages of blockers simultaneously, in-app purchase is required.

What's New in Version 1.2.8

Hi there, dear customer! In this version, we have made upgrading to Premium a lot smoother. There are also a bunch of interface tweaks that generally improve the experience of using the app.

The app has been always free with limits. However, we had a bug in one of our previous versions which allowed some users to use full feature set of the app for free for some time. This release fixes that. Now, by default only “Block Ads” package is enabled, all other packages are disabled, as it should be.

Of course, as usual, we also fixed common blocking problems on popular websites, including:

• GitHub Gist, Hacker News comments are no longer being blocked.
• Bing search should work now without any problems.
• YouTube ad frames get properly hidden (however, some pre-roll ads may still slip through, because filtering them requires capabilities not available in current Safari content blocking APIs).

Important: please launch the app to apply new preinstalled rules.

Customer Reviews

Keeps forgetting purchase

--Update December 18 2016. There was a patch of time that I did not have to uninstall/reinstall to get all the features I paid for. Now neither restore purchases nor reinstalling brings back paid-for features. No response from developer.

--Update to remove a star....
Now I need to delete the app, reinstall, and restore purchase to make any change. Beyond irritating. --

This works, but it is problematic when customizing because the app forgets my purchase EVERY TIME I need to make a change. This means hitting "Restore Purchases" and waiting for a very long cycle before being able to use the app properly. I paid for this to make my life easier, not to toil.

The internet will never be the same.

It will be better! Once you block all that garbage advertising! I love this app. I will be honest, I have never used a different one but I can't find a reason why I would this is worth the .99 price tag and more.
