Daily Mail: A free iPhone app has been replacing an essential piece of equipment for hundreds of doctors: the stethoscope. To use the app, which is called iStethoscope, one presses the iPhone’s built-in microphone against the bare chest for a few seconds, then gives the device a shake. Its motion sensors and camera capture the heart’s waveform, which is then displayed on the iPhone’s screen. Developed by Peter Bentley at University College London, the iStethoscope can capture a more accurate reading than a simple acoustic stethoscope.
