Meet Google Duo, a simple 1-to-1 video calling app for everyone

Google today launched Google Duo, a one-to-one video calling app for Android and iOS. You can download Duo from Google Play and Apple’s App Store,though you may have to wait a bit as this is a gradual rollout — “it will be live worldwide in the next few days.”

Duo is mobile-only, was built to be very fast, thanks to Web Real-Time Communication (WebRTC), and “takes the complexity out of video calling,” according to principal software engineer Justin Uberti. Duo promises fewer dropped calls, and even supports handing calls off between Wi-Fi and cellular connections.

To get started with Duo, all you need is a phone number. You don’t need to create a separate account, nor do you need a Google account. And no, Duo doesn’t use your Google account in any way, according to Google.

Simple interface
Duo is simple from start to finish. To get started, all you need is your phone number and you’ll be able to reach people in your phone’s contacts list. No separate account is required, so you can sign up in just a few steps. From there, you can instantly begin a video call with a single tap. duo_trio

Google said video calls would work even on slower networks by “gracefully” reducing the resolution to keep the call going smoothly.

“For video calls on the go, Duo will switch between Wi-Fi and cellular data automatically without dropping your call,” Justin Uberti, principal software engineer, wrote in a blog post.

Google, owned by Alphabet Inc, said the app would be live worldwide in the next few days.
