When you download 1Blocker for the first time, you already have access to some of its key features — it's called the free mode. This mode was added several years ago to ensure that all our users have access to basic content-blocking protection as soon as they install 1Blocker.
Free features
Access to one of the blocking filters of your choice: Ads, Privacy, Annoyances, or Adult Content. You can switch between these filters freely, but only one of them can stay enabled at a time.
Custom Rules, meaning that all the rules and customizations you create inside the Custom Rules section can be accessed at any moment for free.
1Blocker Premium features
The ability to activate multiple filters.
Scheduled background filter updates. This mechanism ensures your app stays in sync with the latest changes in our content-blocking filters.
