Technology giant Google on Tuesday announced the launch of its video-calling app Duo, a potential rival to Microsoft Corporation’s Skype and Apple Inc.’s FaceTime. In a post on its official blog, the California-based company said the app, which will register people based on their phone numbers, would take “the complexity out of video calling” by letting its users “begin a video call with a single tap”.

The app will be made available on Google’s own Android handsets as well as Apple’s iOS-based iPhone, the blog post said. It added that the app will automatically adjust call quality based on the user’s “changing network conditions”. “For video calls on the go, Duo will switch between Wi-Fi and cellular data automatically without dropping your call,” the post said. It went on to say that all calls placed on the app will be secured with end-to-end encryption.

The app was originally announced in May along with a similar text-based service – Allo – at the company’s developer conference, I/O. The company also develops and maintains a separate text and video-based messaging app, Hangouts, which it will focus on the enterprise sector.
