Not very good
With an iPhone 5 it is very hard to find the heart beat, since you can not hear what you are recording, and it is a very faint record of the babys heart. Besides, you have to pay more to share with other people and you can not export as a sound record so that you can hear in other medias. So, in a way, you can not keep it to the future. Neverthess, it is cool to be able to hear the babys heart even with all those limits.
