Following the announcement of its Assistant digital helper as well as the Amazon Echo‘s competitor Home, Google is now focusing on messaging and videos.

Allo was the first app announced at I/O 2016, and now Duo, a mobile exclusive one to one video service has been unveiled

Allo relies on an extremely simple user interface, which aims at simplifying the way we think of apps of this kind. When you open the app, in fact, you’re immediately greeted with a preview of yourself given by your phone’s front facing camera.

Then a card with big circle images of your contacts will appear; tap one, and off you go. You can toggle the microphone on and off, or you can obviously switch cameras — but that’s pretty much it, because Duo does not aim to be anything but a neat, fast and reliable video calling app.

Mostly, it seems like Google‘s engineered worked to make the app immediate and quick, so much so that the moment you’re making the call, a preview of your video will appear on your recipient’s device — a feature the company’s calling “Knock Knock”.

Allo will be available starting this summer as an Android and iOS app only, and will use your phone number as an identifier. You can check out the introduction video below.
