Google's new app duo is a simple video culling service that's now available for Android and iOS in a way it's a company's answer to Apple's FaceTime and it works very similarly so here's what you need to know about duo first there's not not 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 Android users can see knock-knock regardless of whether duo is opened or not in iOS though you'll only see it if you're in the app otherwise you'll just get a notification saying someone's calling you now 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 in your contact list you can also block individual people from calling you and if knock-knock really isn't your thing you can disable it altogether at this point you might be wondering what makes it different than Google's other communication platform hangouts well according to Google dual is supposed to be way more specialized whereas hangouts is cross-platform and supports group chats and multi way video and messaging duo does one thing and one thing only video calls unlike hangouts it reaches people through their phone numbers not their emails and the best difference between it and hangouts that uses end-to-end encryption because duo is more streamlined it has a very minimalistic user interface before you start a call you'll see icons to start a video call and your contacts during a call you'll see yourself and icons to mute audio switch cameras and end the call video from the other line fills up your screen and that's pretty much it for more about google's duo app check out our hands-on at c-- Netcom it
