Awesome app! Literally has everything any medical professional would possibly need for proper research. Even includes medical terminology word parts, root words, and even combining forms! Ads do pop up but always include a close button so I can get right back to work quickly. Fantastic! Love it!

It has all of the definitions that one would expect. The problem is that even though it is an offline dictionary, it is constantly trying to connect to the internet when I am looking for the definition of a word. Once I turn my internet off, then it brings up the definition automatically. This is very annoying and needs to be fixed. If it's an offline dictionary, then be offline.

very easy and very usefull app. in many nursing books i have noticed that they were written by the assumption that you already know the definition of something and in medical which is huge it was not always necessary that you know everything. when you don't know something and the book you are searching don't have either then you have to search another book but this app had already solve my that problem.
