I've been using The First Hebrew Primer Third Edition to learn the language on my own. It's a great book. But now that there is an app to help me learn the vocabulary, I'm extremely happy. To be able to hear how the words are to be said while I'm looking at the word is well worth the $9. The app seems to work just as advertised with no problems so far. In fact, I think its the best flashcard program that I've ever used for iPhone or the computer. It's really easy to understand and to modify to suit my study needs. BTW, the cost for the box of the same flashcards (minus the pronunciation, of course) is $24. I still miss the feel of paper flashcards, but this is a steal.
