Reeder is a newsreader that supports a number of popular news services. The app aims to aggregate your news stories and make it as easy as possible to browse and read them.
Broad compatibility: Reeder 2 is set up to work with a number of different services. According to the Reeder 2 website, it works with Feedbin, Feedly, Feed Wrangler, FeedHQ, NewsBlur, The Old Reader, Inoreader, Minimal Reader, BazQux Reader, Fever, and Readability.
Convenient interface: Working within the app is convenient and comfortable. The stories can be controlled in a number of ways by swiping, or by tapping and holding to access options. The application's designers have done an excellent job of creating a usable interface for a reader app within a touchscreen environment. You can also pull to refresh from the navigation bar at any time, so you can ensure you're always seeing the most up-to-date information.
Dull design: Although the layout is clean, it is very dull. It is somewhat reminiscent of a newspaper, but with all the visually attractive apps available for browsing news, this seems boring by comparison.
No tabbed browsing: Some other reader applications allow you to open multiple articles in tabs. This is very useful when reading or comparing multiple articles on a single subject. Reeder 2 only allows you to view a single story.
If you're looking for an easy to operate reader application that can utilize a number of RSS feed services, then Reeder 2 is a good option. It's a bit bare bones and only supports single article viewing, but it works well if that's what you're looking for.
