Google duo is an video calling app launched by google on 16 August 2016, Supports in android & ISO devices.
Before coming of google duo I only use whatsapp for video calling to my saved contacts.
But after using google duo i’m very impressed by its high quality video & audio calling in low speed.
As its video & audio is very clear and in high quality, I still have this app in my android phone and I also use it whenever I want too.
Many users are using it and giving excellent reviews about it, just because there is no app in comparison of google duo in current time. If you haven’t used it let then don’t wast your time Install it and experience high quality video calling by google duo.
