Hannah Montana Linux btw?

• Librera
• Obtainium
• AI Wallpaper Changer
• Aegis
• Mihon/Tachiyomi/whatever-the-current-fork-is
• Termux

All of the above managed through Obtainium, directly from the source.

• Bitwarden (Google Play link)
• Eternity for Lemmy (Google Play link)
• HordeNG (taken down from Google play, but if was basically just a wrapper for a web app which you can install easily from the browser anyway - https://horde-ng.org)
• Baby Journal (also a web app wrapper, available as a web app at https://baby-journal.app)
• probably others from Google Play I don’t use that often and don’t remember whether they are open source or not

Three of those are made by me, but I also use them often (that’s why I created them in the first place).
