Just Block

Just Block is an Android app that blocks websites.

Users can manually block websites, or load in blocklists.

Just Block works through DNS filtering. When a user attempts to visit a blocked site, they will be met with a browser error.

Just Block uses AdGuard's DNS server (94.140.14.14) and connects through DoQ (DNS over QUIC).

The filtering and DoQ happens in Rust, while the rest of the app is written in Kotlin.

Just Block is open source under a GPL 3.0 license, and the code is available on Github.
