This is crap! Buy fetal Doppler
My fetal Doppler from angel sounds picked up my babies heartbeat at 10 weeks. I downloaded this to record the heartbeat at 27 weeks and it doesnt pick up anything. I tried it on my phone and iPad-nothing but static. We tried on a friend who is 39 weeks and still only static. The Doppler sounds just like the ultrasound at the OB. A much better choice for peace of mind.
