I can confirm the TT-RSS app (found on F-Droid) is very good. I have used it for years. On the other hand, the web app is not very good, and each time I wanted to read articles on my computer from the web interface, I encountered huge issues (for some reason, the "right click / mark as read" never correctly worked on my computers, or at least with huge lags of several seconds). When my free TT-RSS provider closed, I decided to switch to FreshRSS and could compare several apps for Android; I finally set up the following workflow: free FreshRSS account + "Read You" (found on F-Droid also), and managed to achieve a very similar workflow than previously (with a much better web app).

Could have been due to using a free hosting provider for TT-RSS. I self-host it and have done so for almost a decade with very few issues.

That said as always with software your mileage may vary.

The Read you app looks promising, if a bit different workflow wise. I'll give it a shot with the Fresh API plugin. Thanks!
