This app is only available on the App Store for iOS devices.


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.

Our mission is to give you all the tools to make Safari browsing fast, safe and productive for you.

Happy Safari browsing, friend! You are going to like surfing the web again.

What's New in Version 1.4

Happy Safari browsing, friend! You are going to like surfing the web again.


We added a new rule type called “Make HTTPS” which will secure your requests. Here’s how it works: it changes a URL from HTTP to HTTPS before making a request to website server. URLs with a specified port (other than the default port 80) and links using other protocols are not affected.

We hope this new feature is yet another step towards the better Web.


• Major updates to our rules, including the following:
- Fixed GitHub comments (sorry!)
- Fixed YouTube history not being saved
- Fixed 9to5mac ads (once again)
- Fixed broken DHL package tracking page
- Fixed VOX and Verge cookie warning
• Added haptic feedback when selecting elements in Hide Element mode.
• Numerous other bug fixes and general performance improvements.


A big thank you for using 1Blocker and sending feedback!

If you are enjoying 1Blocker and generous with your time, please consider leaving a nice review on the App Store. It helps us tremendously!

Customer Reviews

1Blocker is is almost perfect

1Blocker is almost perfect, and the inclusion of https is a nice addition. Unfortunately, and this is Apple’s fault, not 1Blocker’s fault. Apple still refuses to allow hosts file access, unless you are jail broken. It is truly sad. 1Blocker should be able to block ads on all browsers, not just Safari. It should be able to do the same for ads inside apps and games. If anyone wants blame to go anywhere, it is with Apple, not the developer. It both saddens me, and sickens me, that the company that used to stand for something good, and respectable. Now, much like many of the devs on the App Store, would prefer to sell our private user data, like we are a side of beef at a cattle auction. Google is just as guilty as Apple is. However, despite the sheer amount of trash on the Google Play Store, at least Google makes rooting is. I highly suggest if you are on a jailed device.

1Blocker is #1!

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!!)

This app is the only one you need

Ahh, there is again.. this app just keep on giving. Make HTTPS for everything!
wooho whitelist now is in the house. This is an icing on top of the cupcake that is 1blocker. Nice new icon btw!

The custom-write-your-own-blocker is the sh*t. Finally I am free from my greedy data provider that feel the needs to blasting already paying customer with interstitial ads.

All I needed is the IP address to the ads server, and away they go..

Also, my feedback email got crazy fast response.. So props to the developer.

This content blocker maybe not the easiest, but surely the best for my needs. Instant purchase.

Thank you 1blocker.
