Total rip off!

Do not buy the in-App heart doppler. ITS NOT WORKING. There is a absolute need for microphone but when its plugged in you cant put the micro snug on the belly and it does nothing. The App suggests a solution for this but the app doesnt allow for it. I wish a refund, do not purchase this App!
