Google released Duo app

Google released Duo, their new video calling app, few days ago. People say its Google's version of Apple's FaceTime, Google just thinks its an app that will solve most of video calling's crucial challenges.

Duo is a video chatting app that, according to Google “takes the complexity out of video calling.” The app is designed to work well with poor internet connection, it has a very simple interface, and so on.

The app also has a unique feature called knock knock, which allows users to know who’s calling before they answer a call.

Just like Whatsapp, Duo uses phone numbers. After downloading the app, enter your phone number, Google verifies it, and you are good.
