The most powerful and the fastest content blocker, used by over a million people on iOS and Mac. 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 has been 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.
• “Switched from Ghostery to 1Blocker for macOS Safari, which uses the fast new content-blocking API, and it seems noticeably faster.” - Marco Arment.
• “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 for iOS in the 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.

What's New

Version 1.4.1

Hello again, friends!

By popular request, 1Blocker now blocks cryptocurrency mining scripts which significantly drain resources on your Mac by executing code in background. Recent reports found out that thousands of websites contain these mining scripts and we recommend enabling Block Trackers category in 1Blocker to ensure your Mac is not affected.

As usual, this version also contains an updated blocker list with fixes and improvements for issues on some websites you've reported. Make sure to manually launch the app after updating to the latest version to have new rules applied in Safari.

If something’s not working right, you have an idea you’d like to share, or you just want to say hello, contact us anytime on Twitter at @1BlockerApp.

If you enjoy using 1Blocker, please leave a nice review here on the App Store. We read everything and it means a world to us. Thank you!

My favorite on iOS and macOS


I have been using the iOS version for a while and have been really impressed. I decided to get the macOS version as well so that I could make custom packages and share them with my phone.

Installation on my phone went smoother than on my Mac, so I think it may be benefical to quit Safari before launching 1Blocker for the first time. I seemed to have some issues with the rule loading properly and having the extension show up in Safari’s settings. After a couple times of restarting Safari I was able to get everything properly setup and I am really enjoying this app.

Bought it for one thing…..

Just another wasted review

I really don’t like facebook (or google for that matter) so I bought this to remove the ‘like’ buttons, prevent resources being loaded etc etc. Didn’t appear to do any of it. Every single web page I opened up after following their FAQ instructions continued to display the buttons even though the ‘hide’ rule was in place. I can’t recommend this at all. I hoped this would be my one stop shop for both MacOS and IOS but I’m not going anywhere near the IOS version after this experience. I’ll stay with Silentium. I would of course request a refund but Apple has done everything it can to make it just about impossible to get one - This isn’t a 99c app - it’s expensive and it doesn’t work as described.

Blocker with nice UI and low processor overhead.


I use 1blocker on both iOS and Mac. Works great in both places. In fact, I see much less “anti-adblock” notifications than I did with uBlock in chrome, which I consider the most comparable blocker.

With 1Blocker, a VPN, and a DNS service that won’t immediately sell out on you (google’s public DNS is probably fine for this), you can surf the web more securely and not generate sweet data which will be sold to highest bidder.

Great work, Salavat and Rinat.

My only note for developers, it’s not clear how often the ads lists updates but I wish they could update in the background outside an actual app update.
