first uses of such an ‘app’ was to monitor vital signs such as a runner’s heart rate, by connecting a sensor from the body to a smart phone.
Smart phones are already in use to take blood pressure and even do an EKG. Currently in development is a product called iTest which will begin by testing for strep throat. This is done by swabbing the throat, placing the swab into a vial of liquid, which is then placed into the iTest device, and in turn, is plugged into the phone to be analyzed.
