Google Duo

Google Duo is relatively the basic application, but the idea behind it is that it’s simple to use and gets the job done. FaceTime is very similar, and works in the same way as the Duo application works. The user pick a contact, start a video call and then click the screen to bring up options such as switching between both the front and rear cameras, mute the microphone or end the call.

There is no group calling, no instant messages, just person-to-person video calls. The user can’t even move the thumbnail of their video around the screen as they can with the other services. At least the video rotates if the user hold their phone in the landscape mode.


Duo has a couple of special highlights, the ability to see the caller’s video stream before the  answer (Knock Knock) and it can switch between the Wi-Fi and mobile data without dropping the call. Currently Knock Knock only works on the Android devices, but the capability is built into the iOS 10 platform, so it could be added to the iPhone application soon.


FaceTime is a video calling application, and is available over the Wi-Fi and 3G / 4G. the user can make a voice call – FaceTime audio – if the user recipient device doesn’t have a front camera, or the user just prefer not to be seen – only heard. Often, audio quality is better than a merely conventional phone call.
