1Blocker application logo

The most powerful and the fastest content blocker, used by over a million people. Lifehacker titled it as The Best Ad Blocker. 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 made MacStories’ list of Must-Have Apps 2015 Edition. It has been also 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.
• “Must have app for all iOS users.”
• “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 in the Mac 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.


The free version of 1Blocker allows one group of blocker rules (e.g. "Block Ads" or "Block Trackers") to be used at the same time. So if you just want to use adblock, you can do that without upgrading to Premium. To be able to activate multiple groups of blockers simultaneously, in-app purchase is required.

1Blocker App Description & Overview

The applications 1Blocker was published in the category Productivity on 2015-09-16 and was developed by Salavat Khanov. The file size is 38.83 MB. The current version is 1.4.1 and works well on 9.0 and high ios versions.

Hello again, friends! This update is focused on making sure 1Blocker looks great on the new iPhone X.

1Blocker Reviews


Great as always!  Patrickl27  5 star

1Blocker is the only content blocker you need! It is very frequently updated with new blockers. If anything you want blocked isn’t, you can add it yourself, all native content blocking functionality is accessible in an easy way! The one thing I wonder is why the new blocker for cryptomining is listed under trackers. I suppose that’s good for free users, who can block trackers and miners at the same time, but unintuitive for paid users if you’re trying to check which cryptomining sites are blocked.


Awesome Blocker  Psicorps  5 star

Works as advertised. Consistant updates. Only Blocker I use!


The very best of all the blockers  Artiste212  5 star

I'm using this on my Mac as well as on my 8+. It works great, and it's easy to suspend blocking or use it with custom lists. This is one of the most effective and complete blockers available, and the software creator has not sold out to any advertisers. Pretty much this is a no brainer - after using others for a while, I've been using this on the iPhone for 18 months and about 10 months on my Mac. It's the best.


Yes  maczombieOG  5 star

Thanks for keeping up development for this awesome app


The best blocker  theBoxHead  5 star

Works great, makes browsing Safari faster and more enjoyable. Highly customizable yet easy to use. This is the one to get.


Does NOT Work  DeeVa27  1 star

(11.12.17) Blocks NOTHING - 100% of ads still show up.


Best FREE Adblocker, period.  fflaguna  5 star

You get to enable the largest list of Adblock URLs for free, with no nagging, no ads, no interruptions, nothing. Again, for free we the full Adblock list of 40,546 rules with NO strings attached. There are many extra toggle-able features that are optional and generally useful only fig you have a specific purpose for them. For $5, they all get unlocked. No price-gouging or exploitative tiers of “special deal!” packages. This filter obviously only works in Safari, due to the Apple/iOS “walled garden” policy crap, but within Safari it works perfectly. It’s clear from the author’s design choices that he’s ungreedy and not in this for a lazy cash grab. That was enough to make me sit down and add this positive review to the list.


Still getting ads  Cailise  1 star

It worked great for quite a while, enough that I paid for premium. In the last couple weeks it’s given up and I’m now seeing ads again. I guess I’m giving up too.


Good Functionality, Bad UI  Bobjtx  3 star

Features are nice, but with the latest update the user interface uses unreadable colors. E.g., Dark purple lettering on a black background. Not sure what happened to UI testing in app development in the last few years, but many developers do a very poor job with UI design. In order for users to see text or buttons on screen, there needs to be CONTRAST. Low contrast fonts (dark fonts on dark backgrounds or light fonts on light background) are a terrible disservice to your users. Please fix!


Stop obsessing;you’ve found it.  Anynomomous  5 star

These guys have brought safety and control to an art form, and once you set it up (with more well thought out variables than any competitor) it runs in the background with a reliability you will only check to make sure it hasn’t disappeared. Best of all it syncs on all platforms (mbook,ipad ,iphone) and doesn’t interfere with serious virus and malware protection software. Do it. You will not be writing one of those regret/warning reviews about this one.


Works well to block ads!  oaksdane  5 star

Fed up with so many ads I gave 1Blocker a go, I’ve had it for a few months now. I admit I have no idea about customising it but that’s okay - I like that I didn’t need to do anything!


CANNOT STOP INTRO.  mactricks  1 star

Intro tutorial repeatedly plays. Tapping 'Close' does nothing.


Ace.  AardvarkGoblin  5 star

As another reviewer said, approximately: so good I forget it’s there.


Best App on AppStore  Electricbambi  5 star

This app WORKS! Get it, seriously.. it’s amazing and packed full of functionality..amazing.


Tried all the competition - 1Blocker is the BEST  herdmasa  5 star

I love this app so much! It’s now installed on my Mac computers and all my iOS devices. All settings are synced between them. App is very customisable. I love being able to whitelist sites when needed, but the greatest feature for me is to be able to block ALL cookies except from the domains I choose. Great privacy :) Thank you!

Rachel Runs!

Literally no difference  Rachel Runs!  1 star

I've reinstalled this numerous times and it still makes absolutely no difference at all. Still getting every single ad and pop up like before.


Great appp  jackson0991  5 star


6163 SA

Really Good AD blocker highly recommended  6163 SA  5 star

I must say probs one of the best free blockers amazing work and congratulations to the developers

Bowie & rage app

Premium, but still get ads  Bowie & rage app  1 star

Just bought premium version and checked the weather app I use. All the ads are now there. Gone back to Adblock. It's a vpn, which I'd hoped to stop using, but it works.


Makes the web useable again  robot_kid  5 star

I forget that it's turned on most of the time, so it clearly does its job! Well worth whatever money I paid for it.

Nickname Taken 123456789

1Blocker is #1!  Nickname Taken 123456789  5 star

Just when I thought 1Blocker was the best, it got better!!! Now you can use "https" for extra safety and security in an unsafe and insecure cyber world! 1Blocker is now beyond the best and surpasses all ad-blockers, cookie blockers and annoyance blockers! And believe me when I tell you I've tried all the rest!!! Using 1Blocker makes me feel so much safer, less nervous and less annoyed when I surf the net! Thank you 1Blocker! (And as I like to state, I do very little reviews because I feel mine would be lost amid the ones written by family and friends who rave about an app but I in no way was asked to write this review and I do not know anyone associated with 1Blocker - 1Blocker is just that good!!)


Simple, easy, and works the way I'd expect it to.  WhyDoYouRequireNicknames  5 star

Looks like this guy can program apps the Apple way. Thanks for keeping the app up to date in a timely manner!


Love this app  JCOSX  5 star

The best blocking app I've tried. Truly excellent.


cuts down many popups - love it!  808User  5 star

Downside is some sites give the "nice/bossy" statement that you have a blocker so cannot continue unless you put them on your white list. pffffffft on them.


Simple, but powerful!  @GMCz  5 star

I've tried a lot of iOS content blockers, and 1Blocker is the best. (All blockers are a bit unintuitive to enable, so make sure to follow the directions carefully.)


Very effective.  Whisk3rBiscuit  5 star

I downloaded this app within a week of it becoming available along with several others and after using them all, I've settled on 1Blocker. A couple of things to consider for new users: take the time to learn how the app works and go slow. Tweak a couple of things at a time and see how they're affecting your browser. There are certainly less complicated apps but those less complicated apps often lack user customizations that I personally want. Of course, if you're not interested in learning how to tweak it yourself, the default settings are still better than most IMO. The app makes it really easy to add your own rules and if personalizing it results in negative behavior, you can just delete or turn off the new rule. Updates seem to come out on a fairly consistent basis and bug fixes resulting from unintended behavior post update have been timely. Most of the complaints I've had have been remedied so not much I can say as far as negative experiences go. My only critique would be to make it easier to see what elements are being blocked and what rules are affecting a particular site without having to connect to a PC or Mac. I'm not a developer so I'm not sure how reasonable that really is. It would also be nice if there was a way to share customizations such as blocked sites and user created rules with the developers. All-in-all, it's a great app if you put a little effort into it. The interface is simple, the knowledge base is full of useful information, and browsing is significantly faster when enabled. Bottom line, it does what it says it does, does it better than most, price is reasonable, and I'd definitely recommend to a friend. Most of the bad reviews I've read on here seem to be user error and not the app itself. I remember when this app first launched and everyone hated it (guilty!) because of that stupid on/off toggle (since removed) and not realizing you had to toggle "allow content blockers" in your settings. Great job Devs and thanks for creating such a likable app.


Good App  Djarard  5 star

The authors suggest you review the app in the update notes. This is the way it should be done rather than annoy you with pop ups about rating them. So here I am.


Just delightful!  Lecter  5 star

1Blocker does its job, and it does it well.


Great app  Dia.Tribe  5 star

Does what it says and does it really well. Regular rule updates are appreciated.


Used to be good  Eveelover  1 star

I used to love this ad blocker but now they want money to use all the features. It won't even block YouTube ads anymore
