I’m hosting my music on Jellyfin. I generally use Symfonium on Android to listen. When I was on iOS I was using this app called Manet, but it was a little buggy. No complaints here though, it fulfills my needs.

Damn, why?

I just edit markdown files with neovim and sync with Syncthing. I don’t have it set up on android, but you sould probably use markor to edit.
