Awful
This app is a ripoff. I am 38 weeks pregnant and went to the dr 2 days ago to hear the heartbeat. All this app did for me was help the baby move around because I was pressing on my belly with the phone. Otherwise all I could hear was the plane flying overhead and white noise. Wasted my money.
