I’ll use any app that remains FOSS so that likely rules out most reddit apps.

You could self host bitwarden if you’re technically inclined. Or use Keepass* and just use syncthing between your devices.

Breezy Weather is an active fork of Geometric Weather (the latter is abandoned).

AKG K371 + Qudelix 5k (for when I want BT support) with PEQ using pipewire built in eq (although this model doesn’t require it).

I may get a pair of Audeze Maxwell down the line, although I’m not sure if the 2.4Ghz wireless is supported on Linux.

I’m waiting for more comprehensive offline support, but it does look promising. DSub and Ultrasonic are other good FOSS subsonic clients (although DSub isn’t being actively developed).

EDIT: Actually looks like there has been some recent activity with DSub, which is great to see.

Syncthing, KeepassDX, F-Droid.

Although in reality, most apps I use could be plausibly replaced with other alternatives.
