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.

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

Happy Safari browsing, friend! You are going to like surfing the web again.


Release Notes:

Happy Safari browsing, friend! You are going to like surfing the web again.

• Major update to our blocker rules.
• Numerous bug fixes and general performance improvements.

Thank you for using 1Blocker! If you have a moment to leave a review in the Mac App Store, we would really appreciate it.

Review by Federico S.

For the rest of us - I bought 1Blocker for iOS long ago. I it has worked perfect ever since. But I did not knew it had a Mac couterpart. So, when I heard about it, I bought it inmediatle. This app is a blocker for all of us that we do not know much about blockers, trackers, etc. It is easy to use and iCloud sync is perfect. I did my first custom rule on a site I visit everyday, not realizing I could block parts of it, whitout compromising what I do need to get from it. Amazing! This app Is awesome. Go buy, NOW!

Does not block ads - 1Blocker is all flash, no substance. YouTube ads are not blocked. Many websites I visit show banners. The “Anti-Adblock” filter does not work. Developers do not respond to me via email and twitter. I am requesting a refund from Apple.

Version 1.3.1
Review by Joey Hoer

Really Great - Overall outstanding. Some features I'd like to see: Turning blocking on/off requires two clicks – one to open the menu and one to enable/disable blocking. As this is essentially the only button in the popup menu, the extra click is unnecessary. A better experience would be to allow one click toggling of blocking. I assume you keep the menu for branding purposes. If this is the case, you could allow this to be a user preference via a "Toolbar item behavior" setting. This would have two options: "Show details" (where the popup menu would still be displayed) and "Toggle blocking" (which would directly toggle blocking without an extra click).

Best in Class - Hands Down - This is a solid app and by far the most customizable ad blocker I have seen—with great support. Every time I send these guys a question I get a swift, detailed, and helpful reply. Be aware that due to Apple's laudable privacy protections, the API they provide imposes some limitations on how ad blockers can detect and block ads; however, 1Blocker seems to work hard to get as much out of this API as possible. You would be hard-pressed to find a better ad-blocking & privacy tool.

Review by Pfine

Best content blocker out there - So great and easy to use! Definitely worth the price. This is the first blocker I’ve used that blocks everything I want it to without breaking websites or messing things up. Couldn’t be happier with it.

What is it blocking? - I wish that like ghostery it gave me a list of what it was blocking. Also wish I had the option of selectively blacklisting sites. I like the idea of blocking nothing except when I arrive at a site that is abusive.
