I’ve been using substreamer to access my Navidrome server from my android phone initially but I just came to learn about Tempo, which is also a nice app. What I like about substreamer among others is the option to let it download fanart from an external source by itself bypassing navidrome. There might be more nice apps, so I’m curious what you folks are using on your mobile devices.
Finamp is very nice. I use symfonium because it is the best app for the task. It auto caches whatever you want, e.g. all 4/5 star songs. The UI is very nice and customizable. The auto playlists are very nice
On pc I use strawberry or the webplayer
