There's one on kbin but not very active yet.

It's probably more subscriptions that people care about, particularly since they are spread out and not always easy to remember.
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).
Yes that's an annoyance but I would expect support for that in the medium term.
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.
For the record, with wireguard you can configure
AllowedIPs
on the client such that internet traffic isn't routed through the tunnel. Basically, don't use the wildcard 0.0.0.0/0 and instead set the wireguard network and the LAN subnet that Home Assistant is on if you need to access other devices.
