Leechblock is a tool that allows to block distracting sites. Unfortunately it is not available for Android. I am looking for any tool for Android - it may be a special browser, it may be a browser + extension combination, it may be paid software, it may be free software with ads. Requirements: - available without rooting phone (with rooted phone it is trivial to edit `/etc/hosts/`) - makes possible to block list of domains, making them unavailable for browsing - it is possible to browse other websites (so ColdTurkey/uninstall browser etc are not a solutions) - strongly preferable, required for paid tool: list of domains may be copied to tool/loaded from file - in case of a paid tool - it has clearly positive reviews and is without any ads
