This is a one-function app; it creates a floating 3D compass rose in your phone’s camera view, with magnetic north indicated by the red color:
The red North arrow can sometimes be obscured by the other direction arrows; however, the rose stays “horizontal” in augmented reality as you tilt the camera, so that you can see the direction arrows more clearly:
Other issues: On my Droid X, the arrow sometimes doesn’t show up. Exiting the program and starting it again usually fixes this issue.
Final thoughts: This is pretty much a demo app, to impress those unfamiliar with smartphones or augmented reality apps. Might prove useful in a few instances where you need to find the relative direction between objects in your field of view. In any case, the price is right.
