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.

Buggy Cloud Sync, Poor Control

Timothy R. Butler

I’ve been looking for something better than Ghostery to allow me to block trackers and the most heinous of ads without blocking “acceptable ads.” Having run an indie site before, I’m not interested in completely depriving publishers of revenue, I just don’t want my computer mining cryptocurrency behind the scenes or loading ads that try to circuvent privacy protections in the browser. It appeared 1Blocker could do this on iOS, so I went ahead and bought the Mac version. I soon discovered the only way I could enable most normal, unobtrusive ads was to go through tens of thousands of poorly labeled rules and turn them on and off one at a time. Synchronizing this with the premium iOS version promised to help, since the iOS version lets me do bulk enabling or disabling of rules, but the sync is broken and whatever I set on that side gets reset and never synced to the Mac. So, I’ve bought 1Blocker for both macOS and iOS and can’t use either. The developer isn’t very responsive, but did suggest I ask Apple for a refund after several months of me trying to reach out. Apple didn’t issue the said refund, unfortunately.

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.

Abandoned now, use another...


With the release of the new 1Blocker X on iOS, the dev admitted that the 50,000 ruleset limit present in the prior version prevented the app from doing the job sufficiently. As such, they rewrote the app entirely, utilizing extensions, and incresed the ruleset massively. Unfortunatey, no such change came, or will come, to macOS, which will remain highly constrained the same as 1Blocker legacy on iOS. Given this, I can no longer recommend it. I’ve moved to uBlock Origin, available for free from the Safari extension gallary and on Chrome, and have found it to work much more reliably.

I’ve tried a few different ad blockers trying to reclaim the internet from the intrusive and resource hogging ads that are EVERYWHERE now, and nothign else has come close to 1Blocker. The dev is repsonsive to reports of new resistant ads and regualrly updates the rule set. It’s super easy to Whitelist sites that treat their readers with respect, and Safari runs so much better with 1Blocker installed.

Put this on your Mac and your iPhone/iPad and thank me later.
