Google's video-calling app Duo

   

                                        
Announced at its I/O developer conference earlier this year, Google has finally made its video calling app - Duo, available to the general public. The app boasts features like end-to-end encryption and claims to deliver a great user experience. Duo is set to take on the likes of WhatsApp, Facebook Messenger and WhatsApp.


Here's all you need to know about Google's newest video calling app.
The 'Knock Knock' feature

Google Duo app comes with an interesting feature called 'Knock Knock,' which previews a short video of the caller before the call is picked. Once the user answers the call, the audio turns on and the two parties can start the conversation. Android users can use 'Knock Knock' directly from the lockscreen without opening Duo. On the other hand, iPhone users will have to launch the app to check who's calling them.

'Knock Knock' can be disabled

'Knock Knock' is only available with contacts that are in a user's phonebook. Users can also block any other users from calling them by disabling the 'Knock Knock' functionality. This feature can be altogether disabled from the app's settings.

User friendly interface

Duo flaunts an immaculate and simple user interface. Before a call is started, users can see icons to start a video call with their recent contacts. During a call, options are presented that can be used to mute audio, switch cameras and hang up the call.

Works well on slow connections

Google claims that Duo can operate well even on slow network connections . Although all calls on Duo are in HD quality, the app can automatically adjust the video quality based on network strength.

Multi-platform

Like WhatsApp and Facebook Messenger is also multi-platform and is available on both iOS and Android.

Bottomline

With Duo, it seems that Google has managed to pick up quite some features from competing instant messengers (IMs) like WhatsApp and made them better with additional features like search functionality. Duo's features are likely to make things easier for users, as they will get search, booking and video calling features in one app. How well Duo manages to do against competitors like WhatsApp and Facebook Messenger, is something only time will be able to tell.
