Since the iPhone 4 has launched we haven’t come across too many apps that use the built-in gyroscope.
However, today we came across Acrossair. Acrossair is an augmented reality app that allows you to search for things with an augmented reality overlay on a live camera feed. The iOS 4 compatible app when running on the iPhone 4, makes use of the built-in gyroscope to add a more silky smooth layer on top of the video feed. Previous versions for the 3GS etc… were a little jerky whilst running.
To demonstrate the differences between the app running with and without a gyroscope, the video below has been created that puts the iPhone 4 next to an older gen iPhone to show the differences between the two.
