Hi Friends,
Google Duo just requires your phone number to get started, and lets you connect with people in your phone’s contacts list. The app is optimized for poor networks, capable of even switching to audio calling if connectivity is weak.
App will soon start supporting audio-only calling as well friends.
I have personally Tried it friend for calling my long distance family members.
Its a very simple light app., just made for vedio calling your friends & Family.
Give it a try friends., and if you like it please do comment & rate friends.
