Doctors are ditching their trusty stethoscopes in favor of smartphones to monitor their patients' heartbeats, according to a recent story. A researcher from University College London has created an iPhone app—which has already been downloaded more than 3 million times—that turns the device into a stethoscope. A free version of the app was introduced last week.
"Smartphones are incredibly powerful devices packed full of sensors, cameras, high-quality microphones with amazing displays," said app creator Peter Bentley. "They are capable of saving lives, saving money and improving healthcare in a dramatic fashion – and we carry these massively powerful computers in our pockets."
