I have used FreshRSS before but I was always annoyed that some sites don’t provide RSS feeds and that even if they provide feeds they don’t provide the whole content through it and only a preview.
What do you recommend for the perfect RSS setup? What are you using? Which app are you using to read them?
I use Flym on Android. Sadly abandoned but still working great. It can import and export OPML, has an RSS search built-in and can retrieve the full version of a piece from the original website.
