North has little in common with other compass apps.
Three characteristics set North apart:
- It uses newest, high precision EMM2015 model of Earth magnetic field developed by NOAA/NGDC.
- It uses custom sensor fusion algorithm that I designed for this purpose.
- It will inform you if there is a mismatch between computed and measured magnetic field. That will help you avoid using misleading reading.
