The mechanisms we use to remove ads from sites are provided by Apple and embedded into Safari, which makes 1Blocker swift, efficient, and secure when it comes to blocking intrusive content. Given that we follow the Safari native content-blocking approach, 1Blocker removes ads from the following apps:

As of now, visual ads served in other apps and browsers can't be blocked because the tools we use are unavailable there.

Also, 1Blocker stops invisible in-app trackers through the in-app tracking filter, which blocks them in all apps on your device through a local VPN profile.

More information here: In-app tracking filter.

The good thing about following this approach is that Apple enhances the level of privacy and security of its customers this way.

The tools we use require iOS 16.0 or later, so 1Blocker is available on a wide range of Apple devices listed here: Apple Support Page.

1Blocker for Mac requires macOS 13.0 Ventura or later.

The app also supports visionOS, so you can use 1Blocker on your Apple Vision Pro simply by downloading it from the App Store.
