I used Feeder on my Android phone for the longest time. Recently set up a NixOS server and enabled FreshRSS on it, with FocusReader as the Android client. It is very nice to manage feeds on a server and have the read/unread status sync across devices.
If you have only used device-local readers before and have a server to spare, I recommend at least trying it!
I have freshrss on a VPS and use the web interface as my client on computers and my phone. Is FocusReader a big upgrade over the native web experience?
