This year, at the Computex 2016, Google came up with a new video calling app called Duo that is available for both Android and iOS. While the messaging service Allo is yet to be made available, Google Duo has been launched for both the platforms.
It can be said that the Google Duo is Google's answer to FaceTime from Apple. It makes video calling between Android phones and iPhones very simple. Google Duo is an intuitive app that can be used by both Android and iPhone users.
Well, Google Duo can be downloaded on your smartphone for free and it doesn't require any complex registration process. All you need to do is just register your mobile number and use the video calling app with ease.
Go through the slider below to know the highlighted features of the Google Duo app. It is quite promising and it might make you want to video chat with your family and friends.
Duo doesn't need a Google account
There's no worry even if you don't have a Google account as the Google Duo doesn't ask you one. You just have to sign up with your phone number and you will get a verification code SMS for authentication purposes.
You can see previews with Knock Knock
The Knock Knock feature is a unique one in Google Duo. With this feature, you can get a preview of the caller before the person on the other end can see you. If you are making the call, you will see a notice that says that your video will be visible to the person on the other end. Eventually, the person you are calling to can see what exactly you are doing at that moment. The Android users can see the caller even on the lock screen, but iOS users don't get this feature as they have to unlock the phone and keep the app ready to see the caller before answering.
You can block a person on Google Duo
Fortunately, there is an option to block any contact from calling you on Google Duo. However, the contact you have blocked on Duo will not know about it and when they call you, they will just hear continuous rings.
No worry! You can disable Knock Knock
The Knock Knock feature might worry you as the person on the other line might see you in real time before answering your call. Of course, you can receive Knock Knock only from people who are in your contact list and you also have the ability to block anyone from calling you. Anyways, if Knock Knock isn't your cup of tea, you can disable it from the Settings menu of Duo. But, remember that you cannot disable Knock Knock on a per contact basis. It will be Knock Knock for either all or for no one.
Video calls are end-to-end encrypted
Google Duo is built on WebRTC that is a standard that lets video, voice and P2P file transfers without the use of software or plugins. Your video chats are end-to-end encrypted, so there is no worry about anyone spying on you and your calls. Google cannot decrypt the content of the calls even if the government insists.
