Mobile apps for iOS

We have just started working on a new project to create a mobile app along with a web-based portal that will help you memorize any material you may need to remember. The idea is simple and well established: it would be good to have an app at hand, which could test you on a bus/train (or anywhere else for that matter) before an exam. It would be good to be able to receive this set of questions and answers from another person who has already entered it into his/her profile as this would prevent you from doing the same thing unnecessarily! In addition, let the application have the possibility to export the list of questions and answers as a clear PDF file that can be sent to any email address and printed out for traditional revising...

We are aiming to have it ready before Christmas :-)
