What is Google Duo?

Created by the Mountain View firm, Google Duo is a free video and audio calling application. Unlike FaceTime which only runs on Apple OS, it works on Android and iOS devices. It is thanks to your phone number that the application can work. It then allows you to contact people who are on your contact list.

In addition, the tool uses an end-to-end encryption system to ensure optimal confidentiality. Above all, the platform has many nifty features like Knock Knock which gives you the possibility to see the live video of your correspondent before answering the call.

All the reasons to choose Google Duo over another app

Google Duo offers many significant advantages that make it a solution of choice. Of course, some of its features aren’t new, but Google has thought about giving it a few extras that could make the difference.

One of the biggest strengths of Google Duo is its simplicity. Indeed, the interface of the application is very simple. To call, all you have to do is press a small button and your contact list will appear. It’s intuitive, simple and efficient. In addition, the application offers users encrypted conversations. These will remain confidential and no one will have access to them, not even the firm itself. This gives you the guarantee of total respect for your privacy.

In addition, Google Duo relies on a phone number like WhatsApp. So, to use it, you don’t need to have a Gmail address or a Google account. Everything goes through the phone number, which means that without a SIM card, you will not be able to use the service even if you have access to Wifi.

Thanks to this type of connection, however, your conversation will never be interrupted. Even if you start chatting with your contacts by connecting to the Wifi of your internet box and then you go out, the cellular network will automatically take over. In other words, Duo is able to switch from one connection to another automatically without the user realizing it.

If your device fails to pick up 4G, 3G, or 2G, the app will still work. If you had network access when you made your video call, you can still continue to have an audio conversation.

Knock Knock, the functionality that makes the difference

The Knock Knock feature is undoubtedly the feature that sets Google Duo apart from the competition. This is a feature that lets you see who is video calling you before you even take the call. However, this function is only operational with your contacts.

Either way, no stranger will think of video calling you directly for no good reason. With this feature, you will be able to distinguish several details that relate to the person calling you, including their location. You can then decide whether to take or decline the call. You have 30 seconds to make up your mind. Once this time has elapsed, the call will be refused automatically.

According to Google, if you know in advance who is calling you and from where, you can get some idea of ​​what state of mind they are in. This will give you the opportunity to prepare yourself for the context of the discussion. To deactivate the feature, go to the “Settings” menu of the application. You will then find the option “Manage preferences” to be able to access the button “Disable Knock Knock. “

Additional features available on Google Duo

Google Duo also offers additional features that make it a popular application:

  • Capture the moment of group sharing: Our meetings have particularly changed because of the Covid-19. Thanks to new technologies, you can now enjoy the pleasures of sharing a video session with friends while preparing dinner or watching a loved one blow out their birthday candles through a video call.

Everyone, including chat members, will automatically receive the photos taken.
  • Send personalized messages: With Google Duo, sending personalized voice and video messages will be easier. You can share photos to simple notes with doodles or text. You can say “I’m thinking of you” or “I miss you” by choosing one of the latest AR (augmented reality) effects.
