On iOS install ReadKit which can interact with a very nice interface to FreshRSS. I self-host FreshRSS and it works perfectly, syncing with the server so when I go to the computer, it is up-to-date with what I have opened. I do not know if ReadKit is on Android.

Reeder is another nice (iOS) client with FreshRSS support https://www.reederapp.com/

Reeder is the app I use the most. It does its job perfectly and nothing more. I love it.
