One of the frustrations of the iTunes Store is the number of supposed "Medical" apps that are not designed for healthcare providers or students. The folks at SoftwareAdvice.com, a commercial site that is paid for through vendor links, offers a great page highlighting some of the best medical software out there for iPhone and iPod Touch. Out of the over 1500 medical apps they determined only about half were actually of use to professionals. I mostly agree with their list. Also be sure to check out the spreadsheet of the over 700 medical apps. It's a great tool for finding apps you never knew about.
