I really like this app but I already paid for it before and now since they updated it I have to pay again?!? I wouldn't mind if they asked for donations after you pay for it since this is a great app but forcing you to pay again is a little much

Haven't had a problem with this app. Good interface and lots of news updates.

This is the most useful app on my iPhone. Very easy to use and extremely helpful. Great to use at study groups and the cards can be edited if they need to be. A must have for serious studying.

Title says it all

One of the best reasons to own an iPhone.
