''The Swivl tracks movement via a sensor while your iPhone shoots smooth panning video. It tilts up and down and rotates a whole 360 degrees.
The Swivl knows who or what you want to film by tracking an easy-to-wear and super compact 3-in-1 sensor. The sensor acts as a sensor for movement, a microphone for crystal clear audio and a remote for fine-tuned Swivl control.''
Swivi you can go from the iPhone 3 to a iPhone 5 and now with iPad 3 and lot more
