One might hope that purchasing the hardcopy of the book for $80 or so would entitle one to free access to the app. Unfortunately this is not the case. Coughing up another $90 for the app itself was difficult to swallow initially, but I have no regrets. It is a much more convenient way to review questions due to its portability, and much more engaging due to the automatic feedback that liberates one from having to flip back to the answers after each question.
One quirk that hopefully will be fixed by the next update is that to answer a question, you have to hit "answer" at the bottom of the screen and then choose your answer from the row of A-E that appears. Really, Elsevier? The app is otherwise sleek and user friendly.
One caveat: you can use this for free across multiple devices. Just hit "buy book" when you want to install it on your second device, and dont be dissuaded by the warning that you be charged $90. If you use the SAME iTunes account as your original purchase, it will be free.
