Google Duo is essentially the search giant’s answer to FaceTime, except unlike Apple’s video calling service Duo works on both Android and iOS, so you won’t have to ignore your iPhone-toting friends.
High-quality free one-to-one video calls over Wi-Fi or mobile data are at the core of Google Duo, but it’s got some standout features as well, most notably ‘Knock Knock’, which lets you see a video preview of the caller before you decide whether to answer or not.
There’s strong security too thanks to end-to-end encryption, and as there’s no need to sign up for an account, you just need to input your phone number to get started. Download Google Duo Apk Android
