When I first seen the price I was definitely hesitant but I decided to give it a tryy anyway and I do not regret it any bit. This is a must have app for ANYONE in the healthcare profession. The amount of information presented is astonishing and worth every penny. The random illness presented at the home screen is also a great touch. As a combat medic in the army I find this an extremely useful resource when my provider is not available and also a great study tool.
