If you are an ownCloud user and waiting for an app that lets you read RSS feeds from websites, here comes an app finally perfect for your needs. The app is still in alpha stage so do expect some rough edges, but works and does what it says.
You can add feeds, folders, view articles, and get all the news updates from blog and sites in a single app. There are something that need reprogramming, like support for unread count and more, but hopefully, we can expect that in future releases.
The app supports export and import from OPML files, so install it from this branch and import your favorite feeds now.
