I just installed Newsify. I wanted an app that allows me to catch up on the news during flights and Newsify aggregates all the latest full text articles from your choice of news, magazine, and blog sites.
Simple to use and has a pretty nice readable interface. I think I selected too many news sources and hence synced close to a thousand articles which caused the app to crash on my old iPad 2. I don't think it would happen on newer devices.
Full text feature is free for 7 days. I bet it can be renewed with a new subscription using a throwaway email address though.
