I purchased HearMyBabyHeartbeatApp20 at 20 weeks pregnant, but couldn’t find anything until 32. But since I could detect my own heartbeat, I knew HearMyBabyHeartbeatApp20 wasn’t a scam. You just have to realize you are in fact using your phone, not a professional medical instrument.
I’m having fraternal twins, so I have a posterior and anterior placenta. Which, as you can imagine, makes it harder to find the heartbeats. But I found two separate beats today, even though one was a little fuzzy.
The main difficulty is finding the heartbeat without the use of the speaker. I understand why it needs to be turned down, but it is hard to rely solely on the sound waves pictured on the screen to find the rhythmic pulse of a heartbeat. If HearMyBabyHeartbeatApp20 could be developed to recognize the rhythm of a heartbeat and alert you that you’ve found it, that would be a huge improvement. But, I am not a programmer so I have no idea if that is possible or feasible. 🙂
