my project is focused on all pregnant women in the world. I want to develop an application with which a pregnant woman with a microphone or an audio receiver and can hear the baby'sheartbeat. everything is based on the vibration emitted by the sound of thebaby's heartbeat is received by a microphone or any soundreceiver that can be used for this. That vibration is reflected in the screen of any iPod or iPad or android in the form of showing the beating heart baby. Any pregnant woman in the world wants this, they go to the doctorand pay just to see this. any man who is going to be a dad in the world would like shared this with women who are pregnant. is an idea that would be used worldwide.
