Great app for photographers. It contains noises made to get kids attention long enough to take pictures such as animal noises and laughing. It also contains womb white noise and mom's heart beating for newborns. It's easy to use and I've amplified the noises as loud as I could to make them easy enough to hear too. May add more sound if this app is popular enough.
