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.


We added a new rule type called “Make HTTPS” which will secure your requests. Here’s how it works: it changes a URL from HTTP to HTTPS before making a request to website server. URLs with a specified port (other than the default port 80) and links using other protocols are not affected.

We hope this new feature is yet another step towards the better Web.


• Major updates to our rules, including the following:
- Fixed GitHub comments (sorry!)
- Fixed YouTube history not being saved
- Fixed 9to5mac ads (once again)
- Fixed broken DHL package tracking page
- Fixed VOX and Verge cookie warning
• Fixed Whitelist rule removal
• Renamed our Safari extension 1Blocker Menu to 1Blocker Button, makes more sense now (thanks Merv!)
• Numerous other bug fixes and general performance improvements.


A big thank you for using 1Blocker and sending feedback!

If you are enjoying 1Blocker and generous with your time, please consider leaving a nice review on the App Store. It helps us tremendously!

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 1.4
Review by WDW1Fanatic

Great App that I always come back to - I’ve been lured to a number of other blockers over time for various reasons, but keep coming back to 1Blocker for use on my Mac, iPhone and iPad. If you are primiarly a Safari user, this is the one to consider. By default it syncs your rules and any whitelist items you create across your devices using iCloud — no more manually entering your bank and other well-used sites as overrides on each of your devices, as most other blockers require. The app does not share data with anyone else, so if privacy is your concern, this is a good one unlike some of the others that may provide more features, but at the cost of your sharing the URLs you visit. …and best, the developer keeps updates coming across both macOS and iOS. This is a great app that keeps working for me.

Review by sglewis

Can’t recommend enough! - Easy to configure, affordable when you think about what it truly does, seems to be very well supported and updated by the author, and as far as I can tell, provides little in the way of issues with web sites and doesn’t appear to cause any browsing slowdowns.
