Develop an iPhone / Android flash card app

I am wanting to create an educational app similar to that of AnkiDroid Flashcards. Mine, however, will be MCAT / UMAT / GAMSAT specific and consist of roughly 600 cards covering Biology, Physics, Chemistry and Organic Chemistry. It is my intention to either A) have an app with full coverage for a set singular fee, or B) have two separate apps. 1 will have a quarter of the content and adds to generate revenue and a paid version add free with full coverage for a set fee. It doesn't have to be super fancy - the content is the most important part. But in saying that, it does have to look appealing. I would like it to have a similar system like Anki, so if you have a look at Anki you will have a better visual understanding rather than me trying to explain in words.
