Excellent, simple, and great call quality.
STOP TRYING TO REINVENT THE WHEEL! If you really feel the need to make a new video chat app then make it interoperable with the existing system you have in place! Hangouts is cross platform and combines all forms of communication into a single app. What genius thought it was a good idea to split it into 3 apps and have it only work on phones. C'mon Google, pull your heads out of your asses!
Very good app. Picture quality is fantastic compared to WhatsApp. Me and my girlfriend use this as she has an iPhone and I've got the Pixel XL. One issue is that sometimes when I call my girlfriend it comes up as unavailable straight away and doesn't ring her end. However if it's the other way around it works fine. Might need some focus on the iOS side!
Duo is much better than other video chat applications such as Skype. The video is generally crisp and the audio good. While in Russia I used it to chat with family back in the States and video was incredibly clear and the audio outstanding. It is not perfect but a large step up from Skype and Apple's FaceTime. My wife and I have Android devices and this app allows us to video chat for free with our kids who have erroneously embraced Apple iPhones. Overall an outstanding product.
Very great 👍 app.. easy to use..with great video & voice quality...but I have one problem..please help me to fix it..one of my relative is also having Google duo.. but whenever I tries to call him.. it just say me to invite..even he is having the app available in his mobile phones...n because of this..I always need to first do him voice call n tell him to call me back..n this happening with my almost contacts..its not working.. please reply as soon as possible...ill be waiting..!!!!!!!😥😥
Two stars is all you get because Google comm apps are a complete mess. This app works, it's simple, call quality is good. I like it. But my parents and wife are the only people I know I've managed to persuade to download it. No one uses Allo. Still using Hangouts on my g voice acct. Why didn't Google just update Hangouts crummy UI with the nice ones of Duo and Allo? Hangouts is somehow still simpler and more elegant because it's just one thing. SMS, VM, video and voice calls, calls to any phone #, IM all in one place. Instead we get a shotgun blast of all these new apps that no one asked for or is willing to download.
