Google has launched their new video chatting app, Duo, which is set to compete with the likes of Apple’s FaceTime and Microsoft’s Skype.
But the app has a new function that could lead to some embarrassment for the caller.
A ‘knock, knock’ function, will give users a glimpse at who is calling even if they are using the camera to check their eyebrows before they answer.
The app was announced in May, and is being released today as a free service for both Android and iOS phones.
The knock,knock function is designed to make video calls seem more spontaneous and appealing.
However, it could also catch callers off-guard who forget they can be seen before the call is answered.
Like FaceTime, Duo only requires a person’s phone number to connect.
Most other services require both participants to have account logins to use their video calling options.
Google has been offering video calling through its Hangout feature for several years, but the internet company is now tailoring that service for business meetings.
Duo is being billed as a simpler, more reliable way to see friends and family as you talk to them.
In their launch blog, Google said: ‘We all know how it feels when a call fails to connect or when video gets choppy.
‘We’ve built Duo to be fast and reliable, so that video calls connect quickly and work well even on slower networks.’
Unlike other video calling apps, Duo will switch between Wi-Fi and cellular data automatically without dropping the call.
Google is also preparing to unveil a new messaging app called Allo – a smart messaging app that has the power of Google built-in and can apparently learn over time.
It will also feature a smart assistant, similar to Apple’s Siri.
Although Google have said Allo will be launching this summer, the exact date has not been specified.
