The app will be competing directly against Apple’s FaceTime, which allows video calls only between Apple devices. It will also compete with Microsoft Skype, Facebook Messenger and even its own Hangout app.
Duo comes with a unique feature called “knock knock”, which lets a person to see live video of a caller before answering and according to Google, video calls would work even on slower networks by “gracefully” reducing the resolution to keep the call going smoothly.
“For video calls on the go, Duo will switch between Wi-Fi and cellular data automatically without dropping your call,” Justin Uberti, principal software engineer, wrote in a blog post.
The app is expected to be available for download in the next few days.
