Great!

I think the women that are giving this app poor reviews, are either using an older iPhone with not the best microphone, or are confused about how it works. Its not a Doppler, so dont expect to hear the blood flow (heart beat) sound that you hear at the doctors office. Im a cardiology technologist so watching the tracing, paired with the sound, I found the HB easily at 20 weeks. You need to push it down on your belly, wait for the line to go flat and then youll see spikes. Those spikes are the sound the phone is picking up from the HB. Id say you should expect them to be 1/2 of a centimetre apart for a HR around 150 bpm, if there is closer to an inch between them, youre probably picking up the flow to the placenta. I like it!
