Optimized for Safari, 1Blocker improves your browsing experience by blocking ads, trackers and other annoying webpage elements, such as popups, persistent cookie consent dialogs, and invasive newsletter signup prompts.

1Blocker makes sites load on average of 50% faster. It’s very secure by design — we can’t track and see webpages you visit.

We think 1Blocker is the best trusted content blocker for iOS and an essential app for anyone who uses Safari.


1Blocker X is a complete overhaul of the original and widely popular 1Blocker Legacy (over 1.2 million downloads), thoughtfully redesigned with a perfect balance between simplicity and power. It was rewritten from scratch and comes with a new enhanced list of filters.

• The first Safari content blocker with over 115,000 rules.
• Regional adblock rules for specific countries.
• User-friendly editors to create your own custom rules.
• Touch ID / Face ID protection.
• Completely new design.


- Block annoying ads (adblock) -
Ads have become a total disaster on many sites by ruining the browsing experience. No one likes to see ads that pop over the entire screen.

- Sites load faster -
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.

- Improve your productivity -
Besides ads, webpages often contain distracting elements (like “You Might Also Like” boxes) that disturb your workflow and productivity.


We believe 1Blocker is better than anything else available. Here is why:

• We don’t make deals with advertisers.
• We don’t see webpages you visit.
• We can’t track you and 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.


1Blocker has been featured in The New York Times, TechCrunch, Lifehacker and many more.

Seems better

Update - a year later and I decided to give this app another try to see if things work any better for me. And they do. Pretty good on my iPhone X running IOS 13 - so far. So I’m updating to 4 stars. We’ll see how things go for a while.

Original review - While I’m sure this app does its job, it also breaks lots of sites unless you toggle off the “block trackers” switch - which is one reason why I got the app in the first place. It too frequently destroys the normal browsing experience. So your choice is either to put up with broken sites or cripple this app’s functionality after paying for it.

Oh, wait - there’s a third option: use something else. That’s what I did and I’m much happier (except for the money I wasted on this app).

1Blocker X

Just upgraded to 1Blocker X, and I have started to play with the settings. I welcome the ability to block those annoying little side bars that want you to tweet, fb, etc. I don’t care to share what I think of a website. I also don’t care to know whether others “like” something on the websites I visit. Being able to block all those websites that don’t have https is a plus. It’s possible this was already offered in the previous version, but I didn’t spend much time finding out. I was just glad to see those pesky “cookies” disappear. I don’t mind paying for anything if it works. The previous version worked well for me, and I think this new one will, once again, be money well spent. Thank you for this new version.
Update-Well, I have now benefited from the paid app for several years. It delivers as promised, and I have not had to worry about my phone’s safety. Great app for those of us who want peace of mind while using their cell. Again, thank you Indie developer.

Works perfect

Many OTHER ad blockers have fallen into disrepair, not having been updated in ages or at least visibly updated and losing their effectiveness. This one bucks the trend and goes full throttle ad blocking with great configurability such as easy white listing. I only wish that some websites that I visit and enjoy had ads that weren’t so utterly obnoxious that they hijack my Safari with a new page to announce “You’ve own a prize! Click OK!” And then I can’t find my way back because swiping back just loads the ad again. UGH. Well, this blocker effectively stops that crud with the latest policies. I’m sure it is a full time job just keeping that up to date so the app cost is perfectly reasonable. Technically the app is above all the rest since they’ve managed to implement more than 50,000 policies using a modular system. Awesome. Now if only websites realized their ads were so obnoxious that JUST MAYBE less obnoxious ads would result in less ad blocking and more revenue.......
