Heartbeat Listener description

This application has a fun and non-medical purpose. It requires headphones and works like a stethoscope filtering and amplifying the sound from the microphone before the rebroadcast of the headphones.

To use it, turn on the application, plug in the headphones, launch listening and as if it were a stethoscope, affix the microphone of the device on the chest at heart level. You can record at any time what you are hearing and then replay or share your recordings on social networks.

The quality of listening depends on:
-The quality of the microphone equipping your smartphone (or tablet). Following models and brands, the sound quality can range from a clear and audible beat to no beat sound at all.
