Its a great app. The picture from grays anatomy are very precise and detailed, as well for the text,originally from the 20th edition .(i think). I'm a medical student and i have been through alot of material. Some parts example the skull, is written very superficial in normal text book,despite its importance, but here every bone , and structures that are decribes are quite useful. But the pictures are hard to imagine, and only to describe it theoratically. My suggestionmis to use this app and a skull or some atlas with real specimen like rohen or the grays atlas, the 39th edition for best image(i think). Use it to prepare before practice. Its a good tool for those hard working students who are willing to dig deep Cons: the app alone is abit slow, hard to navigate,if i dont know this book before it would take ages to find what i want. Developer should think of a way to reinvent it. Then it will be a awesome app. Still good for the price. Deserve a. 5
