Baby Phone Mobile is a type of child monitoring app, wherein one part of the app installed on a device works as a receiver while the other works as a transmitter.

The transmitter part is held near the child, and the receiver can be carried along with you. Receiver mentioned here is just another instance of same app installed on other device.
The app opens up beautifully and asks for accepting its terms, once you are done with that, you can calibrate the microphone as per you.

Once you are ready to stream the video, the app provides you with a password which you need to enter at the receiver end.

Now its time to stream and watch your cute little baby. On a decent network streaming works nice, but some loss of frames is possible on a slower network.

So guys just give this app a try, although it is paid, but its free for taking a trial.
So just go ahead and watch your little baby, even when you are not around.

The app is available on playstore, for more details please check the site too.
