Main Difference – Google Duo vs Facebook Messenger

The main difference between Google Duo and Facebook Messenger is that the Google Duo comes with features like encryption, knock knock – a unique feature, which has been optimized for crisp video, and is able to swap between Wifi and data connections more efficiently. Let us take a closer look at both Google Duo and Facebook Messenger and find out what each application offers and which one has the upper hand over the other.

Google Duo | Features, Performance

The Google Duo application is Google’s latest video chat app. But why Google is introducing this app at this time when there are established applications like FaceTime, Facebook Messenger, Skype and what does Google Duo really have to compete with them? Google Duo comes with simple and fast features to provide the user with a great video chat experience. Knock Knock is a unique feature in Google Duo that displays a live video preview of the caller before it is answered. This is similar to peeping through the door’s peephole before knocking on the door. Duo promises to offer the same effect.

What is Knock Knock

Knock knock is a special feature that lets the user see a video preview of who is calling. The preview acts as a doorbell for the conversation to happen. The Google Duo was released at the Google I/O event held recently. The application is a video calling application which can be supported by iOS and Android platforms. One of the highlights of the application is that the Google promises to provide a great user experience regardless of whether it comes with a fast or slow connection. Like WhatsApp, Google Duo makes use of the phone number rather than a Google Account. This lets the user call anyone who is present in the phonebook with ease.

The main purpose of Google having the Knock Knock feature is to make video chatting fun and worthwhile. When a video chat call is made, it gives a glimpse as a video of the person who is calling from the other side. This is a unique feature yet to be seen on any other messaging platform up-to-date. This could turn out to be a killer feature to outperform its competitors and gain market share.
