I am able to keep track of my baby the Dr. Said wasn't there. I am not sure how far along I am pregnant but the baby is definitely there. Heartbeat is any where from 130-165 bpm
Bunch of crap. It kept saying plug headphone Jack in even though it was already in.
Disappointed. Not working properly
I don't like it
Lots of frequency interference In some clips you can hear the heart heat fine, and while I have my head phones on I can hear it, but there is a lot of static and high pitched frequency sounds overlapping it when is recorded so its very hard to hear the heart beat when you play the recording back. Also, it stopped allowing me to record when i put off rating the app. So that was annoying.
Fenomenal Por fin he encontrado una app que funcione y puedo grabar el sonido del corazón de mi bebe y luego poder compartir con mis seres queridos. Es muy emotivo. La he usado con la máquina Angelsounds Fetaldoppler
