Google Duo is a new video chat app that just debuted specifically for mobile. The Verge describes the FaceTime competitor as “fast, easy to use, and devoid of complicated bells and whistles. You tap on the face of the person you want to call, they answer, and you have a one-on-one video chat going.” The single-minded approach is meant to be simple — including the setup process that merely involves a sign-up and confirmation — and “no accounts to create nor friend lists to maintain.” Duo is simply tied to your phone number and contact lists, and is available for both Android and iOS. It does not enable conference calls or desktop calls.
