- Block annoying ads -
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.

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 :)

This app saved my ipad

This is the best app I have ever installed. My 5th generation iPad had become totally useless. It was totally bogged down with SOMETHING. Per advice from Apple, I deleted history, cookies, and website data, quit Safari, and then did a complete restart. The problem was still there. I spent a good six hours trying to fix the problem with no success. I was ready to throw my iPad in the trash, but I found a recommendation at Apple to install an add blocker. 1Blocker was recommended, so I installed it. My iPad now loads in a flash.

I have about 50 news bookmarks that I visit every day. After I installed 1Blocker, several of them now pop up the message, “
We see that you’re using an add blocker. Click “here” to disable the blocker to use our site.”. NO WAY! I delete the bookmark instead.

Works as promised!

Have been using this delightful app for over a year now, throuth two iOS betas (I am a sucker for punishment) and it has been flawless in keeping my Safari browsing ad and page-clutter free. Am not certain of how the API works, but a feature request would be to allow the inclusion of multiple ad tracking sites - I am thinking of using Dan Pollock’s host file list - a perennial on all my computers. Other than that minor quibble (it may not even be possible as per the limits in the API) I have been quite satisfied with the results!
Much thanks to the devs, you have made this user quite happy!
Warmest regards,
Deborah Terreson.
