Google Duo is available for free on the App Store. Watch the video below to see it in action: If you don’t like the idea of this, Knock Knock can be turned off in Settings. Duo looks a bit bland, though, since it can’t do group calling, video effects or text chat. This means when calling someone, the other person will see a video preview of yourself, and vice versa, though the recipient’s video won’t start until they answer the call. Nabbing those users who want to video call their Android friends is one avenue for success. When it comes to the actual calling, Duo makes use of a feature it calls Knock Knock.

So what other features does it have? Well, the app can switch between cellular and Wi-Fi so your call shouldn’t drop if your connection gets patchy, while all calls are end-to-end encrypted as well. Of course, the other person needs the app too, but Duo allows you to invite others via the app easily. You’ll notice the UI is incredibly understated and settings are few and far between – simply select a contact to call them. Sign up with your phone number and then enter the code you receive via SMS to verify. First, download Google Duo from the App Store (as of right now, it’s rolling out globally, so if it’s not available in your region’s App Store yet, it will be soon.)
