Miniflux is great. I've been self-hosting it for about two years now. It's rock solid. The OP uses an android app, but I've been getting a lot of use out of just having the website on my phone as a webapp. The software has fever and greader api support, so RSS apps like Reeder (mac and ios) and FeedMe (android) work as well.
I really love that you can target scraping rules (using css) and block/allow rules (using regex). It's a wonderful software.
