The mobile live broadcasting service formerly known as Yevvo is now known as Air -- an app that lets you stream live video to your friends. Still in beta mode, the Air app still focuses on live-streaming video as Yevvo did. However, there's no longer the option to replay content, so your friends can only watch a stream that is happening live. You can record at the press of a button and your friends will be notified you're broadcasting.
This feature of the live-stream app gives Air a SnapChat quality. When you stream live video, you do have the option to capture images and create a Flashback for later. You can also encourage friends to broadcast by requesting an 'Encore.'
The nature of the Air app is more private and intended for use between friends.
