Google Duo Aims to Make Video Calling Super-Easy

Google on Monday launched Google Duo, a one-on-one video calling app that runs on iOS and Android. The app will be available worldwide in the next few days, said Justin Uberti, principal software engineer at Google. Duo switches from cellular service to WiFi, and transitions from high-speed to lower speed wireless service smoothly, promising to let users continue video calls irrespective of their location and service speeds, although video degradation may be apparent on slower services.
