My Compass XL 对比 +Compass+ 的使用情况和统计数据

Compass XL is a tool to search bearings (azimuth) using the device built-in magnetic sensors and the device GPS. You can also easy switch from true North and magnetic North. The compass accuracy depends on the performance of your device. If it works perfectly, this means your sensors are perfect, too. If it is inaccurate, please check that you aren't being affected by a magnetic field and the sensors become weakened by age.
