It’s OK but not great
20 years of doing hand surgery so I know hand anatomy and trying to teach it to students pretty well. There are two main problems with this app; the nerves appear in too many layers (you should be able to toggle them on and off) and the veins are always on with the arteries. Veins are almost irrelevant to teaching hand anatomy however they are overpowering in the is app obscuring the important detailed arterial anatomy. The resolution is pretty disappointing for 2015.
