Some others that I use:

* NextCloud -- client for personal NextCloud server; this app is used primarily for file sync, with other features accessed with other apps. (https://nextcloud.com/features/?filter=Clients#android-clien...)

* KeePassDX -- password manager, shares DB with KeePassXC on desktop, which is synced via NextCloud. Also functions as a TOTP authenticator. (https://www.keepassdx.com/)

* DAVx5 -- CalDAV and CardDAV client; keeps mobile calendar and contact list synced with private NextCloud server. (https://www.davx5.com/)

* AntennaPod -- excellent FOSS podcatcher. (https://antennapod.org/)

* KDE Connect -- desktop sync tool; allows file/clipboard/keyboard/audio/etc. sharing between phone and a Linux desktop. (https://kdeconnect.kde.org/)

* Kore -- remote control app for a Kodi instance running on your LAN. (https://kodi.wiki/view/Kore)

And I don't see F-Droid itself mentioned -- it's the most popular repository of FOSS software for Android, with an accompanying app: https://f-droid.org.

> I don't see F-Droid itself mentioned

F-Droid itself is great, but I find that the NeoStore front end to F-Droid is superior because it has multi-repository capability, offering a long list of alternative apk sources that can readily be verified for quality.

Additionally, the official F-Droid app creates unnecessary friction for GrapheneOS users they refuse to address: https://gitlab.com/fdroid/fdroidclient/-/issues/2914

Neo Store looks interesting, but the readme in the GitHub repo includes emojis in the feature list, which is a bit of a red flag for me, especially since the project appears to have started only two years ago.

What is the concern about emojis in the feature list?

It's an indicator of LLM output, so calls into question the integrity of the software itself.

I also like AntennaPod for audiobooks--fewer apps that way.

I'd add that KDE Connect works great with Gnome too

Can't believe I've never heard of Unexpected Keyboard. Installing immediately. Thank you.

Thanks for the links. I am concerned about supply chain attacks and such with FOSS tools these days. It seems like the easiest attack surface. In my dev opinion it’s not if it’s when. Kinda sucks and I think the adversary is moving faster than the provider. (I have created and maintained public domain software but not currently. Now I’m crapping on the thread sorry. But no one else is sorry for crapping on threads…I need to stop over thinking or maybe just close this tab)
