Google Duo is one of the easiest video chat apps out there, but it’s not only for video. You can make audio-only calls, too, and the sound quality is much better than a typical phone call’s. We’ll show you how.

Like with video calls, the voice calling feature works on iPhone, iPad, Android phones and tablets, and computers through a web browser. It’s just a matter of choosing “Voice” instead of “Video” when starting a call. We’ll cover each of these platforms.

Starting with mobile devices, first, open the Google Duo app on your iPhone, iPad, or Android handset. Now, scroll up and select a person to call.

Google Duo will now ring on the recipients’ end. In the voice call, you’ll see a blank blue screen with a couple of buttons for muting your microphone, ending the call, and enabling speakerphone.
