Google Duo: a simple 1:1 mobile video calling app

Video calling is the next best thing to being with someone in person, but too often it can be a frustrating or complicated experience. You shouldn’t have to worry about whether your call will connect, or if your friend is using the same type of device as you are. It’s no wonder that nearly half of us never make video calls on mobile.

Google releases Duo - a simple 1-to-1 video calling app 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.

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:

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.

And all Duo calls are end-to-end encrypted.

Note that this does not replace Hangouts video calls:

  • there is no desktop version.
  • there is no group calling.
  • there is no screen-sharing or other advanced features


Give your friends a wave with Duo! Google will roll out Duo for Android and iOS and it will be live worldwide in the next few days. Download here
