Google's Duo finally became available to the public at large. It's a video chat app, which makes it super-simple to just dial one of your contacts, introduces the feature Knock-Knock in Google's Duo, which shows you footage from the caller's selfie cam before you choose to pick up, and promises the highest possible quality of audio and video that your connection can provide.
