If you live in PA, have Highmark as your insurer and an iPhone, a new iPhone app called Health@Hand is ready to help you find a Highmark-plan doctor in the neighborhood. More than that, it can research common first aid situations and with the Symptom Navigator, touch an outline of the body and see what symptoms turn up. (Great for hypochondriacs!) The iPhone app was designed by Atlanta-based A.D.A.M. Release. A.D.A.M website.
