The most powerful and the fastest content blocker, downloaded over a million times. Lifehacker named it as The Best Ad Blocker. Essential app for anyone who uses Safari.

Unlike other adblock apps, we can't see what sites you visit and track you. That’s because 1Blocker is a native Safari content blocker, not a shady VPN server. We are supported entirely by our users, there’s no “acceptable ads” program.


1Blocker made MacStories’ list of Must-Have Apps 2015 Edition. It has been also featured in The New York Times, TechCrunch, and many more.

• “I like 1Blocker enough that I’ve stopped thinking about blockers.” - John Gruber, Daring Fireball.
• “Must have app for all iOS users.”
• “Does exactly what you want it to do, and the customer support is fantastic. Highly recommended ad blocker.”


- Block annoying ads (adblock) -
Ads have become a total disaster on websites by ruining the browsing experience. No one likes to see ads that pop over the entire screen.

- Save battery, data and time -
Independent tests by Wirecutter, NY Times, and BrooksReview confirm that 1Blocker cuts data loaded by sites on average by over 50%.

- Protect yourself online -
Many corporations track your behavior and what sites you visit. Online ads are not safe and may serve you malware even on major sites like Forbes and Yahoo.

- Improve your productivity -
Besides ads, webpages often contain distracting elements (like “You Might Also Like” and subscription boxes) that disturb your work flow and productivity.


1Blocker comes with almost 50 000 built-in blocker rules. It is very configurable.

• Block ads, trackers and other annoyances. Make browsing over 2x faster.
• Tap to hide any annoying content with our visual editor.
• Support sites you love by whitelisting them.
• Create your own custom blocker rules (hide elements, block sites and cookies).
• All your settings are synced over iCloud.

1Blocker is also available in the Mac App Store.


We believe 1Blocker is better than anything else available. Here is why:

• We don’t make deals with advertisers.
• We don’t and technically can’t track our users.
• We have no customer data to sell.
• We are bootstrapped and self-funded. No investors. Made by a tiny two-person team.


While most other adblock apps block content by filtering elements of an already downloaded page, 1Blocker uses native Safari content blocker technology (API) to tell Safari in advance what should be blocked. This vastly improves efficiency, doesn’t slow down Safari, and saves battery life.


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

Our mission is to give you all the tools to make Safari browsing fast, safe and productive for you.

😑Premium Doesn’t Block 3rd Pty Cookies

I used the free version of the app and was pleased with the ad blocking for the most part but I was irritated by constantly having to delete 3rd party cookies in website data. I saw that the premium version allowed blocking of 3rd party cookies so I purchased it. As a side note, it wouldn’t have cost me anything if iOS still allowed us to block 3rd party cookies specifically (like we could before) rather than ALL cookies which, of course, affects logging into accounts 🤬😡❌.

Anyway, after enabling the option in 1Blocker, I noticed I was still getting the exact same 3rd party cookies showing up in website data as before. I checked the app and their website for any info related to my issue and found nothing. They only offer two methods of contacting them that I found: email and Twitter. I used both and got no reply. Almost every option in Apple’s “report a problem” menu just redirected me to the app developer. I finally chose an option that would prompt an Apple representative to contact me and only then was I able to explain that the app developers were unresponsive and I couldn’t get the app to function as expected. I was issued a refund and am happy to go back to the free version while continuing to search for an app that will block 3rd party cookies such that I’m not constantly clearing out the website data to remove them.

Developer Response ,

Hello. First of all, I'd like to apologize for not getting back to you in time. We receive a lot of emails and being an indie developer, sometimes it's hard to reply to everyone quickly.

Now, let me give you an explanation about this issue with cookies (it is also available in our FAQ both on our website and inside the app). Here's the thing: websites still save them to your computer. However, if you have cookie blocking rules enabled, Safari would ignore them when doing requests to those websites, as if they are not present.

For this reason, inspecting this feature by looking at the list of stored cookies won’t be helpful, you need to inspect network requests and see what cookies they carry.

Let me know if you have any questions and I'd appreciate if you could update your review :)

Trash app now, no longer works

Used to be a great app, but then the developer legacied it and put out a new app. And it’s pretty ridiculous that if we’ve paid for premium on this (the same $5 cost mind you) we don’t get access to 1Blocker X. Also ridiculous that you have to pay for separate access from iOS to MacOS. You’re better off investing in a quality VPN that can do this and more, I know that’s what I’ll be doing. Shame, you’ve lost a loyal user because of the nickel and diming

Completly stopped working

Does not block ads anymore, latest iOS on iPhone 11. Tested on multiple websites, quit and relaunched the app, rebooted phone, quit and relaunched safari, deleted the app and reinstalled, disabled and re-enabled ad block in app, nothing worked. Developer is now selling different similar app, the money i paid for this app went down the drain.
