I’ve been using my own app JamRSS until I switched to Read You because it looked better.

Feeder

Inoreader. Syncs across multiple devices too.

Focus Reader is excellent... https://play.google.com/store/apps/details?id=allen.town.focus.reader

I use the Nextcloud News app with Nextcloud.

Thunderbird does RSS reasonably well I believe.

gReader Premium. It is no longer available on the Google Play store, but you can still find it on alternative sites like Aptoid and such, I think.

I've tried LOTS of them. This one is the best, in my opinion. Works with Feedly and other online services, as well as stand alone subscriptions.

Here is the URL to the Play Store as it still shows up for me, but might not for you.

Although not an android app, I'd like to mention Firefox' Feedbro add-on. Since Mozilla recently announced (if I'm not wrong here) to make the desktop add-ons available in the mobile version, maybe Feedbro will be part of it?

Miniflux is my favorite. No native app but the web app works really well on mobile. And the tight integration with the Read-it-Later app Wallabag is just brilliant. I love the combo.

@Kalcifer I use friendica as my rss reader

Readrops

Feedly works well fire me.

Bazqux through the browser works great.

I self host Tiny Tiny RSS.
