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).

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.
