I like https://newsboat.org, though it is command line and since I started using an android RSS reader, I've stopped using newsboat as much.

I also like Feeder for Android, free, no ads, scrapes full articles in a wonderful way: https://play.google.com/store/apps/details?id=com.nononsense...

Feedly. Occasional sponsored story. Android and desktop Chrome synchronised.

Since you asked, I'll drop it here. I built Brook, and it works well enough for me that I often forget I built it, or that it isn't just part of Firefox: https://github.com/adamsanderson/brook

Bonus: If anyone uses it, you'll increase the global user base by several percent.

QuiteRSS on desktop. Flym on Android. Both are free with no ads.

I used Flym for a while and went to download the source one day, in fear of it suddenly disappearing, and apparently updates are blocked by Google, and the dev gave up? I'm very curious to know more about it: https://github.com/FredJul/Flym

Since then I've used Feeder, it's similar (also free, no ads, can scrape full articles) but is missing a few things that I liked about Flym. It was easy to export my list of feeds (OMPL file, I think) and import into Feeder: https://play.google.com/store/apps/details?id=com.nononsense...

My own, of course. https://airss.roastidio.us

well Google Reader back then was the best and obliterated any single commercial reader's offering. Since Google nonsense about Google+ and Reader's demise, well inoreader isn't that bad as a RSS client.

Feeder.co is pretty good.
