Launched in 2016, Google Duo is Google response to FaceTime.
The app is available for both Android and iOS systems and has no compatibility issues between the two.
It can work on low bandwidth networks allowing users to make high definition video and audio calls.
It is fast and straightforward with only your phone number as the login method.
The app was designed to slowly replace Hangouts.
It incorporates one-tap calling, and it can switch from mobile to WIFI data to make sure you get the best quality.
It also incorporates the Knock-Knock features by turning on the caller’s camera to see who is calling.
However, the app is not used by too many people, and it is not compatible with other mobile operating systems.
You cannot use it on multiple devices. It was designed only for video calls, so it does not have text or audio calls features.
