Google duo is launched by google for android and ios users to connect with friends and family with high definition video chat Upto 720p hd based on your mobile camera specifications.Due to this the video call consumes more mobile data.we need 8mb data for a minute.If we make a 10 min call , it consumes nearly 80 to 90 mb.If you prefer for quality, then get google duo.The app can shift to wifi from mobile data if network available.First and foremost the app looks good.The app icon is really nice.
The app is based on phone numbers.we can call only the people who are only in our contact list and they should have duo app on their mobile.knock knock feature is available .This feature allows us to see live preview of us before calling to someone, so that we can adjust the our place of our chat to bright place so that we are visible and comfortable.we can also make audio call if dont have data to make a video call.ultimately the app is really good for mobile users.I recommend this product for all users.But we need data flowing in our mobile for long calls.
