Google has unveiled its latest video calling app, which has been dubbed by the company as “Duo.” According to Google, the app has gone live globally and is available on either Android or iOS devices.
Google revealed that Duo works off your phone number and provides simple one to one video calling to bring you face to face with everyone you care about, without needing to sign up for a Google account.
The app’s Knock Knock feature gives a preview of incoming calls from your contacts, so you can see what’s up before you answer the call (this feature can be switched off, and only works on iOS if the app is already open on the user’s phone).
Duo works on wifi and cellular networks, and will hand over a call from one to the other – so if you’re on a call and move out of wifi range, it’ll move onto the cellular network, or vice versa, with no intervention from you, the company revealed.
According to Google it has optimised Duo to connect faster than other video apps, and to ensure it stays in sync, even on slower networks like 2G. All calls are encrypted end to end, making them secure from start to finish.
