eRoentgen Radiology DX and Gray's Anatomy

I just downloaded the Grays Anatomy app. It has all the classic illustrations from Gray's anatomy with the labeling. For 1.99 it is a much better deal than the Netter anatomy app. It has more illustrations but the labeling is not interactive.

A second app I saw was eRoentgen Radiology DX. This app looks like it is an interactive implementation of the American College of Radiology's appropriateness criteria. Its screen shots look well organized and was written by a radiologist. The price was steep at 49.99. If he lowered the price I could see it being quite helpful for the primary care Docs that don't have radiologists to easily consult with prior to ordering a study they don't order often.
