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.
I didn’t know about Symfonium, it looks quite nice. I used it alongside Tempo for the last days, I prefer them both to substreamer. Thanks for the hint, anyway!
