Great, but not complete.

Its a great tool for learning and checking out most of the bones. By "most" I mean that not all of the bones have great detail. For instance the sphenoid is shown as just a cross section of the cranial vault, it shows some features, but a stand alone 3D image of the sphenoid would be great. This goes for all of the bones of the cranial vault, you cant just look at the frontal, parietal, or occipital bones by themselves, they are articulated with the rest, which is great, but if you need to learn visually and look at all the features of the bones inside and outside, you might be disappointed with some of the bones. Also the Os Coxae are missing, you should be able to view these as stand alone bones because they have a lot of features that a professor might test you on. Other than a few disappointments, I would recommend this app to anyone who needs to learn the skeletal system, its the second best thing (other than actually holding the bone in your hand).
