I’m running Navidrome on my Raspberry pi (4). On my phone (Pixel 8) I use Symfonium to connect with Navidrome. When I’m travelling I use Tailscale + Mullvad + Symfonium to play music from my rpi.

Have you tried Tempo (FOSS)?

I use LawnchairRelease, a fork of one of the devs from Lawnchair. You can also use the original Lawnchair Launcher

Forgotten apps: Lawnchair(Release) together with Arcticons. Very minimalistic!

Maybe you can try Discreet Launcher. It’s 1.41 MB.

Yes, it’s a real picture. I saw the bird at a building site.
