Google’s new application, Duo, is a basic video-calling administration that is accessible for Android and iOS today. Close by the forthcoming informing application Allo, it’s one of two correspondence applications Google reported recently at its I/O gathering, and one of four through and through from the organization. As it were, it’s Google’s solution to Apple’s FaceTime, and it makes balanced calling between Android telephones, and from Android to iPhone, extremely straightforward. In spite of the fact that the two gatherings need to download the application to start visiting (not at all like FaceTime, which is prepared into the dialer of perfect iPhones), it’s as yet a natural application to utilize.
You’ll see previews with Knock Knock
Duo’s unique feature is Knock Knock, which gives you a preview of who is calling by firing up the camera on the other end of the line. If you’re initiating the call, you’ll see a little notice that says your video is visible, which means the other person can see what you’re doing right at that moment in real time. Android users can see Knock Knock regardless of whether Duo is opened or not (like on the lock screen). On the iPhone though, you’ll only see it if you’re in the app. Otherwise, you’ll just get a little notification saying someone’s calling you.
You can disable Knock Knock
Before you worry about seeing anything you don’t want to see from the other line, know that you can only receive Knock Knocks from people who are already in your contact list. You can also block individual people from calling you. (By the way, when you block a person on Duo, the person won’t know it. When they call, they’ll just hear your line ring and ring continuously.)

Its interface is super simple
Duo has an incredibly user-friendly and intuitive interface. Before you begin a call, you’ll see icons to start a video call and your recent contacts (sorry, there’s no audio-only option). During a call, you’ll see yourself (in a small little circle), and icons to mute audio, switch cameras and hang up. Video from the other line fills up your screen and that’s pretty much it. If you’d rather have your camera fill up the screen (for example, you’re touring a house to the person on the other line), just tap the preview circle and your view will switch.
It’s different than Hangouts
At this point you might be wondering what makes Duo different than Google’s other video-calling service,, and you’re not alone if you think the company . But according to Google, Duo is supposed to be way more specialized. Whereas Hangouts can be used on desktops, supports messaging and group chats, and has multiway video for collaboration (and its interface reflects these extra features), Duo does one thing and one thing only: video calls on your phone or tablet.
