Question record a heartbeat ????

I am trying to find a program that will help me record my heartbeat to play later. I have tried a fetal monitor using audacity but too much noise. I know an iphone works using the microphone but my budget allows only a smartphone.

I would appreciate any ideas. Maybe a cheap voice recorder? microphone?

thanks :
