I'm reading this on Feeder, which a free RSS app I found on F-Droid. Works for me

The Reeder family of RSS apps goes for engaging scrolling on iOS.

I came here via NetNewsWire. iCloud sync is flakey but that's the only quibble. Oh, and you can't yet export starred articles unless you fiddle with SQL.

I'm reading this on my RSS reader right now :)

ReadYou on Android and NetNewsWire on iOS are pretty good. Both native and open source

I am pretty happy with Readwise’s Reader
