The android apk is at github releases (below link), and for the moment being I'm not concentrating on make the onboarding for fresh users a main priority. For now trying to implement useful features for users with an already list of following. Maybe if you can test it with your npub in a smaller screen and let me know of any advices to fix. Blocked words should work, the add button on the bottom was covered by the new note (+) sign on the web version, that's why you couldn't add words there. I will for sure improve the bottom adding of relays/words and make it more central and user friendly to add.
