Dont buy this.

I have not yet been able to use the app. Every single time I have tried to use it, it has crashed. All I do is open it, search for a term, and select the article I want, and the app crashes. Consistenly. You ought to avoid this and use Safari instead. I should have read the reviews, so its my own fault now.
