Fast and secure Safari content blocker that improves browsing experience by blocking unwanted content and protecting you from trackers.

We are legit, deeply care about users’ privacy, can’t track and see what sites you visit.

We think 1Blocker is an essential app for anyone who uses Safari.


1Blocker X is a complete overhaul of the original and widely popular 1Blocker (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 120,000 rules.
• Regional adblock rules for specific countries.
• User-friendly editor 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.

- 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 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 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 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.

• Must have app for all iOS users. - MacStories
• The best adblock for iPhone. - Lifehacker

What’s New

Version 2.1

Even when we’re quiet there are many things moving and changing. Thank you for being so patient.

This update adds partial whitelist — a feature many of you waited for a long time. It allows you to configure each blocking category for a specific site and do things like unblock comments and ads for a site, but leave trackers and other content blocked. This feature was asked by many advanced users and it adds further flexibility to the app.

Speaking of whitelist, it is much faster now to add a site to the list (up to 25% faster in some cases).

Of course, we also updated our ruleset and fixed a ton of sites. Thanks for all the reports you sent us!

Last but not least, this update contains many tweaks that make the experience so much better.

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!

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.......

Solid Upgrade to a Great App

I loved the last version because (colorful interface notwithstanding) 1Blocker has the very Apple-like quality of being forgettable—it just works! No ad blocker is perfect but 1Blocker is by far the best I have found to date, having tested almost a dozen. (I am not, after all, a professional reviewer—just an adamant hater of scummy ads.)

Despite the fact that 1Blocker “just works,” it also seems to be one of the most flexible, powerful ad blockers on the market. The included rules can be examined and switched on/off with great granularity, or by category; custom rules can be added by hand, or if one is so inclined, with the in-built Safari extension; and sophisticated whitelisting capabilities are included, although considering how rarely 1Blocker’s defaults break sites (almost never in my experience), the deluxe whitelisting options seem almost superfluous.

This upgrade delivers a noticeable speed boost and, near as I can tell, lays the groundwork for even greater flexibility and functionality as this major release matures.

Bottom line (or, in the lingo, “TL;DR”) is that this is a superior product in a space where everything is imperfect. It may not be perfect or a “magic bullet” but it comfortably leads the pack. I for one am very pleased to support the developers behind it!

Works As Advertised Despite Steep Price

I will admit I paid a steep price for the ad blocking app. Compared to others out there on the App Store, this is the most expensive app I purchased specifically for ad blocking purposes. This app works very well and performs as advertised. I would say this app resembles UBlock Origin, the best ad blocking internet extension on PCs and Mac. Two reasons: First, you can hide certain elements of a website you do not like. And second, there are so many filters you can enable on this app. If you're willing to spend a bit more money compared to others, you will not be disappointed. I am using this app on a 10.5'' iPad. Hopefully, this app will get updated regularly. Also and for others wondering, THIS DOES NOT BLOCK ADS IN APPS. You need to use the app called Ad Blocker to enable that.
