This app, even if not worldwide known, is brilliant and very useful. I know is not possible to have it completely for free, however only Med student and few others can be interested in something like that. Moreover sometime even if all organs and apparatus are wonderful and well designed they are not complete , some arteries are missing, some ligaments are not fully visible and so on. To conclude I just want to say that I cannot fully understand why from iPad is not possible to access the website instead to be obliged to download the app. That is not very convenient because in the web site you have that fantastic list of body parts (which is not present in the app) that allows you to easily find every part of the body you desire to see .
