Health professionals have iPhones too, so that it's no wonder that a lot of apps have been developed especially for these users. Rather than just a fun gadget, the smart phone and its medical apps have become an important tool for the doctor of today. According to a recent review in the journal Clinical Infectious Diseases,  “Modern technology has revolutionized the clinician's ability to have vast information resources available literally at one's fingertips. The advent of the smartphone-an integration of the mobile phone with an ultraportable computer, web browser, multimedia player, and camera, has given clinicians the capability to merge their information and communication resources into one compact handheld instrument."[3]

Another review article in Healthcare Informatics predicts the future of medical apps: "Many innovative organizations are looking to provide access to electronic records and other clinical data through smartphones. Plans are already being formulated to leverage the devices to facilitate patient handoff and sign-out, as well as to link charge capture with quality measures. Cutting-edge organizations are looking to create actionable information for clinicians through software that can analyze data, track patients' progress, and send out alerts when conditions worsen."[4]

We have compiled a list of some of our favorite apps for both the consumer as well as the health professional. The list is relatively short compared to what is available. The apps described here are usually for the iPhone, iPod and iPad, but there are similar apps for the other phone operating systems. The best thing to do is try out the free apps first [5] and then move on the paid apps. [6] Some apps are also available for a free try out for a limited period of time.
