A 3D compass for the iPhone 4+ and iPads. It uses the accelerometer, magnetometer, and gyroscope to point north no matter what orientation your device is in - even upside down!
Use it to find true north when youre in the woods. Use it to find up when youre lost in a snow cave. Or just have fun.
3D Compass Max uses OpenGL for lightning fast rendering and state of the art signal processing for fast and smooth compass operation.
