Duo, a new, simple video calling app

Duo is a video chat mobile app developed by Google, available on both Android and iOS. Google Duo will replace Hangouts for video calling within the suite of Googles apps.


  • HD 720p video
  • Optimized for low bandwidth mobile networks. The app optimizes WebRTC and uses QUIC over UDP. Optimisation is further achieved through the degradation of video quality through monitoring network quality.
  • “Knock Knock” – an Android-only feature which 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”
  • End-to-end encryption by default,
  • Google Assistant support,
  • Use of phone numbers to allow users to easily call people from their contact list,
  • Automatic switching between WiFi and mobile data.
