Google Duo has been around since more than more than a year now and the company feels that it would be more easily accessible if introduced on the Web. The mobile App is being used by millions of people around the globe as it is very convenient to place video and audio calls to your friends, family and colleagues. The Web service will help reach to more people and could also provide more features to enhance the overall user experience.
9to5Google was the first to report about this and explained how Google is wanting to expand Duo beyond the Android/iOS Apps:
This development ultimately means a much wider reach of devices that can access the growing service. Google Duo has, up to now, only been available in the form of an app from the Google Play Store or the iOS App Store, and on its Smart Display platform.
Just like the previous web versions of Google Allo, and more recently Google Messages for web, the web version of Google Duo will support Google’s own Chrome browser and likely other major browsers such as Mozilla Firefox and Apple’s Safari. Also like those web apps, Duo will presumably take advantage of browser notifications for incoming calls.
Google is also expected to include the current features of the Duo App like “knock knock” and “recording video messages” for the Web. Recently, the Google Duo App hit a billion downloads on Google Play Store, which indicates how big and impactful the service is compared to WhatsApp and similar video calling Apps.
