Google new app Duo is a simple video-calling service

Google Duo is a simple one (1) to one (1) video calling app for everyone and a video-calling service that’s available for Android and iOS today- all you need is a phone number.


Characteristics of Google Duo:

  • Knock, knock! Google Duo video call is here
  • Google’s Unveils New Video Chat App That Works on any Phone
  • Google wants to change the way people video chat on mobile devices with the release of its new Duo app.
  • Duo, which is positioned to rival Apple’s FaceTime, is available to iOS and Android users.
  • After downloading the app, all a user needs is a phone number to reach friends in their contacts list who have Duo.
  • People who prefer to screen their calls will enjoy “Knock Knock,” one of Duo’s differentiating features that allow a user to see a video stream of the person calling you before they choose whether to answer.
  • From a technical standpoint, Google is touting a seamless video calling experience on the app, even if two friends use different operating systems.
  • The duo is also designed to adjust to changing network conditions, so when bandwidth is limited it will reduce the video resolution without the call becoming choppy.
  • A user could also begin a call on Wi-Fi and walk out the door, switching to cellular data, without the quality of the call being impacted.
  • Google first revealed the existence of Duo at the company’s annual developer’s conference in May.
  • The app is available for download today and is expected to be released worldwide in the next few days.


Google and Apple have battled each other for years for superiority over mobile users. Apple has preferred its superior devices, like the iPhone but Google has battled back with its Android operating system. Google is a series of mobile apps that are more flexible and compatible with a broader set of devices than Apple’s apps.


Google has gradually offered its important software and internet services likes- Google Maps, Google Photos, and Google Docs, to iPhone customers. All of those apps were exciting alternatives to Apple’s exclusive apps likes- Apple Maps, Photos, and Notes, because they work on a wider variety of devices, including Macs, Windows PCs, Android devices, and iPhones.


Duo lets you place video calls between Android and iPhone users, and sizable increases the universe of people with whom you can hold a video conversation but people can only use FaceTime to call others who have Apple devices.


Google Duo compare with FaceTime, Skype, and Facebook Messenger


Google Duo

  • The Duo app is downloadable and free through Google’s Play store and Apple’s App Store.
  • When you open the Duo app, there is just one button: video call.
  • Tapping that loads your contacts list, and from there you can choose whom to call.
  • The duo starts streaming video to a recipient as soon as the call is placed, meaning the person you are calling will be able to see you waving or making faces before he or she picks up.
  • Google calls this feature Knock Knock.
  • It can be inactivated in case you have friends who are likely to make inappropriate hand nods.




  • You place a call directly through the iPhone’s contacts list or through the separate FaceTime app.
  • The recipient does not see the video streaming until after the call is answered.


Facebook’s Messenger


  • Facebook’s Messenger app, the video-calling feature is embedded in the corner of a message box, so it is hard to find and not intuitive to use.
  • In fact, every call I have ever made with Messenger has been by mistake.




  • The video-calling feature is in a place similar to Messenger’s, in the corner of a message box.
  • More annoyingly, to find other Skype users you have to manually add them to your Skype contacts list or toggle on an option to synchronize your address book with Skype.



FaceTime is just as natural as Duo. So, I realize that there is no exciting reason to use Duo over FaceTime to call iPhone users. In the world, the human being is always welcomed new technology.
