Steth IO is a Stethoscope in a Smartphone
Now there is a new device, a “smart” stethoscope, that helps doctors detect and diagnose heart problems. Steth IO, is built directly into the protective case of a physician’s iPhone (models 6 and higher). Functioning like a stethoscope, it lets physicians listen to and measure heart rates or lung sounds by running an app and holding the phone up to a patient’s chest.
