Google have released Duo,
an insanely simple video calling app for Android and iPhone. The
FaceTime rival is now available for download and free to use. The aim is
to make video calling as easy and reliable as possible, Google Duo
stops you worrying about whether your call will connect, or if your
friend is using the same type of device as you are. The entire user
interface is designed to be intuitive and simple to use, a video call
can be initiated with just a single tap. Duo works well even on slower
networks, and will switch between Wi-Fi and cellular data automatically
without losing your call. Another cool feature is “Knock Knock? which
lets you see live video of your caller before you answer. watch the video below
