Recently I wrote about native medical applications soon to be available for iPhone. Until you wait for them to come out, why not try some already available medical web applications for iPhone.
A.D.A.M. Symptoms Navigator is one such application.
With this tool, you can easily find out what to do about any symptoms — wherever you are! Learn self care, when to go to the doctor, and when it is an emergency. Whether you are traveling on vacation with your family, or on a business trip and feeling ill, an extensive library of symptom guidance is at your fingers – all within just a couple of taps.
Take a look at the video demonstration I made.
