Pocket Anatomy and Pocket Brain Video Demonstrations:
Ever since I first bought this app (2 years ago, I think) it kept updating and developing very frequently.
I used it as a Physio student and now I use it to illustrate my clients anatomical explanations I give them. I teach anatomy myself and I must say this app consists of adequate information for almost any undergrad student that studies anatomy. Bottom line, a very good app, very easy to use, frequent updates and the quiz mode is very motivating to keep learn more and more.
