Over the past year, I have noticed a surge in the number of medical colleagues using the Apple iPhone. I can no longer recall how many times I have seen students, residents, fellows, and attendings pulling the device out of their white coat pockets. This is not surprising, considering that Apple has had phenomenal success with the product. The company sold over a million units within 3 days of launching its latest iPhone 3G S model.

Besides its phone, web surfing, e-mail, and personal information management (PIM) functions, the iPhone has become a veritable tool for medical reference and calculations. Ye olden days of the Palm Tungstens or Treos as the must-have tool for students and residents are no more.

As an interesting side project, I decided to create a Squidoo page on iPhone medical apps. This will serve as a growing catalog of useful medical applications for the iPhone. If your favorite app is missing, do not hesitate to leave me a message.

Financial Disclosure: No, I do not own Apple or related stocks, but maybe I should.
