The only app I ever need in my med school


I use this app in my med school in a daily basis. It is very rich in information and photos. Thank you for iPhone 6 Plus update!
** The only thing that I hope developer may fix someday is its search method. If you look up a combined word, eg; juvenile Diabetes, the same word will be shown in search results. However , when u click it, the root of the word will be displayed (in this case,diabetes) and you should look for you word manually through scrolling. Which sometimes can be really cumbersome. Interfering with the functionality of this app as u might use it while training and ever second count.

Happy with my purchase


I purchased this app months ago. I use it as a dictionary and occasionally for pronunciation and it works great! Like most professional medical books I wish it had been a little more affordable. It is probably my most used resource.

A classic


This volume has been a classic for decades, more than half a century and it has always received top recommendations from my colleagues. I believe it should be a part of every personal medical library.
