Baby Walkie Talkie listens to your childs room and sends data to the parents phone when there is any sound. The family does not have to leave the application open all the time on the phone. Thanks to the push notification, information is sent to your phone 2 times a minute as the sound comes from your childs room. At the same time, information is sent to your phone in case of internet interruption or phone shutdown. When the video package is purchased, you can monitor your child in real time.Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
