Google showed DUO: video messaging app
As a part of Google I/O, Google introduced a video messaging app named DUO.
Like the Ello, it is also one-to-one encrypted. The interesting feature of the app is the live stream of the function. It is a feature that shows the caller in a live stream. In other words, if your friend calls you, you will see him or her before answering the call. This feature is called as “Knock. Knock”.
Google Duo will be available in this summer on Android and iOS along with Allo.
