Google Duo is Google’s answer to FaceTime; simple, reliable video calling that just works. It has a simple interface, with very few bells or whistles and takes seconds to register via your phone number, much like WhatsApp.
Duo uses a new protocol to transport the video calling packets between devices. QUIC (Quick UDP Internet Connections) promises better performance than other technologies, meaning better quality video, and less stuttering when in a call, even over slower connections.
Duo also has a fantastic feature that will maintain the audio part of a video call when the connection speed drops. I’ve experienced this multiple times and it’s great; when you are video calling a third party and the connection drops below a specified level, the video will pause, but audio will remain clear and smooth so you can continue your conversation, when the speed increases the video comes back. This is brilliant when compared to an app like Hangouts or Skype which would experience stuttering video and
audio if the speed decreases, meaning you cannot carry on your conversation until you move to a better coverage area.
Then there’s the killer feature, Knock Knock. This allows you to see the other person’s camera footage before accepting the video call, so when I call the missus, she can see what I’m doing before picking up and decide whether to pick up the call based on what she sees! Oo er.
So, Google Duo; it’s very simple to set up and use, performs very well and has a couple of very impressive features that differentiate it from other video calling apps. The only downside is you can’t use the app on a device that doesn’t take a SIM card currently.
Give it a go and see what you think!
