Read You, probably the best RSS reader available on Android. The bad: still in beta and no sync with Feedly (yet).
Sync for Lemmy, also the best client for Lemmy in Android by far. Design and user experience are delightful. Bad: ads with an expensive subscription. Good: with adguard DNS ads disappear.
Mammoth is a great app with a nice user experience. I really liked It when i was on iOS.
