A 3D compass for the iPhone 3GS, iPhone 4+ and iPads. It uses the accelerometer and magnetometer to point north no matter what orientation your device is in - even upside down!
If you have an iPhone 4+ or iPad2+, 3D Compass Max will use the gyroscope for much better responsiveness for silky smooth motion.
Use it to find true north when you're in the woods. Use it to find up when you're 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.
