This is one of the few apps that looks beautiful on the iPad. I had it installed on my iPhone but didnt open it often during clinicals or school, just because I thought the navigation was impossible to deal with on a small screen (the scrolling over for charts, the tiny font, etc.) I ported it over when I bought an iPad, and now I open it up all the time. Its written more in book format, but I especially appreciate the navigation now -- its great, and very intuitive.
I do wish there were more "interactive" features for the price (more drawings/images, sounds), so Im giving it 4 stars. But its great as a reference tool, and I recommend it.
