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.

Best and only blocker you’ll need. Just Buy it Now.

In the age of trackers and cookies on the internet you are paying for the “free” internet with your data. With the data that is being collected these sites and services know more about you than either you or your loved one. These pesky trackers gather great insights into every aspect of your online life. One way to combat this on Safari is to install this app. Combine this 1Blocker X with a VPN (possible extra device 1 Blocker X could offer) and you will greatly increase your privacy on Safari.

The feature set of this app is very granular and there are even more granular settings for the geeks of you who want to create special rules. 1 Blocker X has ad blocking specifically for German and Russian users in the sub settings for those of you need it.

I always like to support Indy apps and this app is indispensable to my iOS life. Worth every penny because it works tirelessly in the background to negate most tracking.

Those who know what it takes to make a app like this will appreciate the work and I most certainly appreciate the 1 Blocker X dev team.

Once great, but categories let it down

This was once one of the best blockers on the market. However, changes to the category groupings have made it unusable. Previously (and still on the desktop version), EU cookie notices, crypto-miners, and other annoyances were in separate categories.

Now they are grouped together under “Annoyances”. The problem with this is that some sites are broken by blocking EU Cookie notices, as it’s a legal requirement. A site breaking because you blocked a crypto miner is fine (that probably isn’t a site you want to use anyway), but almost all sites have cookie notices. Before you could turn off blocking for those categories independently, now you either have to deal with cryptominers and such as well, or have lots of site break.

If they bring back granular categories then it would be 5 stars, as the basic ad-blocking is great. But 1Blocker X is sold and priced as much more than an ad-blocker and design changes have made those features broken.

Hello, James!
We really appreciate your feedback, your review is very helpful. We just wanted to let you know that we will consider returning EU Cookie notice section back. Please, stay tuned!

The best blocker on IOS

It’s a one off purchase not an annoying subscription like most apps are trying for these days. For less than 2 beers you get the best blocker out there.

I found it frustrating that the older version is no longer rated 5 stars because people are moaning that they upgraded that app only for this new one to come out and calling the dev greedy. That app was over two and a half years old and we seem to live in a world where people want everything for free and forgot that the dev needs to earn an living.

So in short if you want the best app for blocking the ever increasing rubbish on the net and are not deluded to think that quality is free get this app.
