Google Duo is the tech giant’s newest video calling app.

It’s specifically designed to remove all the hassles from making video calls.

All you need is a smartphone and your phone number.

Google created the app so that it will maintain connectivity even on slow or crowded networks.

The app’s Knock Knock feature allows you to see a live video of the person calling you before you answer.

Of course, you’ll only see videos of people in your contact list and can turn it off whenever you want.

Google promises end-to-end encryption on every call.

Simple, glitch-free and secure video calling?  We’ll give it a shot.
