Better quality than Hangouts. Not as sharp as Skype but simpler than both. I just want to go to my app and go straight to video chat and the simplicity of this app allows just that! I like how the setting/phone options fade off the screen so there aren't any other distractions on the screen during the call.
Good connection, clear video, easy to use, works great! I'm saying goodbye to Skype & Facebook Vid Chat. From now on I'm using Duo. If any of my friends don't have it, well they better get on board because I'm not using anything else.
I increased the rating to 4 as a bug seems to have been fixed. But the quality is not that good as of late. Voice often gets delayed and compressed. Also video synchronizing issues happen too often. It's probably due to congestion. See if you can address it.
Best VoIP solution so far. Great audio / video quality. Love the minimalist UI, does what its supposed to do. Had some minor issues with bluetooth accessories integration while receiving calls, hopefully will be fixed soon.
Simple, easy to use app. Works well. Google keep it simple and idiot proof. People like face time and apple because Apple doesn't keep changing useful apps constantly. I would have used this ages ago if it was built into Android.
Video quality is very bad... Tried calling a phone beside me with full coverage and no luck... Very bad connectivity and video quality. Even when the call is not connected the recording is very unclear. I see vertical purple coloured lines all over the screen.
