I use this app already on two iPhones and now wanted my Insert DX Kindle Fire (3rd generation) as baby station, that's why I bought the app here in the Amazon store again. The iPhones were found immediately and the impression of the app is exactly like the other devices. When I started the baby monitor, but an error message came that the microphone was not found. Apparently No device has none at all, then that can not go. As a parent station but it went. So make sure if the device has a microphone before buying this app!
