My heart is talkative. Joy, sorrow, excitement, calm, pleasure, pant, fulfillment, dissatisfaction ... I always mutter something by one person. There are not many things that can not be heard well, but before you hit a stethoscope on your chest, your feelings will always be high.

I created this application "pocket heart sound" to convey the interestingness of this cardiac language. It also introduces the history of stethoscope and trivia of heart sound. There is no more pleasure if you become interested in heart auscultation.
