Google Duo – Simple video calling app
High quality video calls for Android and iOS.
Google Duo is a simple one-to-one video calling app without any difficult menus or clutter. It so simple and video call centric app that it has not other menu or feature except to make quick and clear video calls. Available for Android and iOS. Duo takes the complexity out of video calling, so that you can be together in the moment wherever you are.
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.
Fast and reliable
We all know how it feels when a call fails to connect or when video gets choppy. We’ve built Duo to be fast and reliable, so that video calls connect quickly and work well even on slower networks. Call quality adjusts to changing network conditions to keep you connected — when bandwidth is limited, Duo will gracefully reduce 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. You can start your call at home, and continue seamlessly even when you head out the door.
Preview incoming calls
To make calls feel more like an invitation rather than an interruption, we created a feature in Duo called Knock Knock which lets you see live video of your caller before you answer, giving you a sense of what they’re up to and why they want to chat. Knock Knock makes video calling more spontaneous and welcoming, helping you connect with the person before you even pick up.

Optimization is further achieved through the degradation of video quality through monitoring network quality. “Knock Knock” shows a live preview of the caller before the recipient picks up, which Google says is to “make calls feel more like an invitation rather than an interruption”.
