With more than half a million installs, Google Duo - the simple one-to-one video calling app is already among the top free apps in the Google Play Store.
Justin Uberti, Duo Technical lead shared the news on twitter and said that the app was now available worldwide. We have been playing around with the app for some time and it does what it is made for. Its simple to use, quality is good over WiFi but it gets a bit dodgy over LTE.
The company says the app is optimized for poor networks and can switch between mobile data/WiFi on the fly without interrupting the connection. We have also heard of a new update in the works which would enable audio-only calling.
