Works fine
This is basically a "sun compass" and it does what is promises...shows you where true north is when the sun is shining. As a photographer I use it frequently to estimate when good lighting conditions might be present for other times of the day. The iPod Touch doesnt have a built-in magnetic compass so this is the best and only app that gives you an indication of direction.
