Duo is Google’s answer to Apple’s FaceTime, and the company swears that the video-calling app is totally different than Hangouts. Google’s new app, Duo, is a simple video-calling service that’s available for Android and iOS today. Alongside the upcoming messaging app Allo, it’s one of two communication apps Google announced earlier this year at its I/O conference, and one of four altogether from the company.
