About

1Blocker lets you block obtrusive ads, sneaky trackers, and annoying elements on sites. With 1Blocker, you’re safe online and nothing will distract you from enjoying sites. 1Blocker is very easy to use — just flip a couple of switches to start blocking ads and trackers. The app will automatically receive cloud updates to the built-in filters silently, so you don’t need to do anything. It’s as simple as setting and forgetting. 1Blocker is a fully native app designed to extend Safari naturally. It’s lightweight and doesn’t drain your battery by taking up your device’s resources. The blocking itself is super fast because Safari does it itself. We only provide filters to Safari and don’t modify webpages in any way. This vastly improves efficiency because Safari knows in advance what should be blocked. So, with 1Blocker, sites load on average 2-5x faster. It’s important to note that not all ads can be blocked though. Some sites use techniques that make it impossible for us to block their ads using currently available features for Safari content blockers. SECURE BY DESIGN 1Blocker is secure and private. It doesn’t have access to webpages and doesn’t track you in any way. We believe that privacy is not for sale. That's why we don't have an "Acceptable Ads" program. We stay independent, and the only way we make money is through direct sales of 1Blocker in the App Store to you. ADVANCED CUSTOMIZATION 1Blocker is a highly customizable content blocker, providing the possibility to create powerful custom rules. It allows you to create custom rules that block any URL by providing a regular expression or hide any element by CSS. It also lets you block cookies. (Available in Premium) AVAILABLE ON ALL DEVICES 1Blocker is available for iPhone, iPad, and Mac. Your preferences and custom rules are always in sync through iCloud no matter which device you're using. FEATURED IN THE PRESS 1Blocker has been featured in TechCrunch, Lifehacker, MacStories, Macworld, and many more. FEATURES AVAILABLE FOR FREE • The ability to enable one category (for example, Block Ads only) • Whitelisting sites right from the Safari extension • Whitelist synchronization between devices via iCloud FRIENDLY SUPPORT Send your feedback at @1BlockerApp on Twitter or via email. Your feedback is always very welcome and considered for the next release. We have been making 1Blocker since 2015. We believe it’s the best all-around package currently available in the App Store.

Very worthwhile upgrade

"I’ve been using the original 1Blocker since launch and it’s probably saved me countless amounts of time and bandwidth. The asking price is a nothing compared to the headaches saved by a great ad blocker."

Mission critical app for iOS/iPadOS/macOS

"Actively developed and regularly updated, this app is one of a handful of things keeping me from switching to a different mobile platform that supports true network filters. The subscription is worth it to block the thousands of in-app trackers on device rather than with third-party servers simultaneously with safari filters. I wish this app was also available for tvOS but would not be surprised if it's forbidden by the platform owner."

💡 Frequently Asked Questions

Got Questions About 1Blocker: Ad Blocker?

Q.Is 1Blocker: Ad Blocker free, or does it require a subscription?

1Blocker: Ad Blocker is listed with a baseline price of $0.00. Check the in-app purchase options in the App Store for complete tier details.

Q.How do I enable 1Blocker: Ad Blocker in macOS and iOS Safari?

On Mac (macOS): After downloading from the Mac App Store, open the application once, then launch Safari -> click "Settings" (or Preferences) in the menu bar -> select the "Extensions" tab -> locate "1Blocker: Ad Blocker" and check the box to enable it. On iPhone/iPad (iOS): Go to iOS "Settings" -> tap "Safari" -> tap "Extensions" -> select "1Blocker: Ad Blocker" and toggle it ON.

Q.Why is Safari ad-blocking much faster and lighter than Google Chrome?

Chrome extensions traditionally execute heavy JavaScript inside every web page to inspect and block URLs on the fly. Safari uses native compiled JSON rule lists processed directly by Apple WebKit engine in C++, preventing ads from even starting to download without executing third-party code in your tabs.

Q.Does this extension work in Safari Private Browsing mode?

Yes! On macOS Sonoma / iOS 17 and later, go to Safari Settings -> Extensions, and ensure "Allow in Private Browsing" is checked. This ensures the same clean and ad-free experience while safeguarding your incognito sessions.
