My Compass XL vs Luopan Compass

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.

Luopan brings the ancient Chinese geomantic compass to your iPhone. Whether you practise feng shui, study the I Ching, or simply want a beautifully rendered directional tool, Luopan gives you a faithful multi-ring compass that responds in real time to the way you hold your device. The rotating dial mirrors a traditional luopan with four concentric rings rendered in SwiftUI Canvas. The innermost lacquer circle holds a classic red-and-silver magnetic needle. Surrounding it are the eight trigrams (Ba Gua) of the I Ching in the Later Heaven arrangement, then the 24 Mountains (Er Shi Si Shan) with both Chinese characters and pinyin transliterations, and finally a precision degree-tick ring calibrated to one-degree intervals.
