Description

From the listing uploaded by “appupdater”.

This is a small size and efficient aircraft style compass and earth Gauss meter ( Static Magnetic Field meter ). The accuracy of this app depends on the type of sensors used. For best compass accuracy, please perform calibration and true north adjustment before use. * If the phone do not have a magnetic sensor, this app will not work. This is mobile phone / touch pad design limitation, not software problem * Note: Mobile phone sensor can only detect DC type magnetic field, that is the earth magnetic field. When measuring power line magnetic field ( for example, 50 / 60 Hz AC) , the result is not accurate, or even no reading at all. This app is for daily uses only, please use professional instrument for accurate measurement. If you encounter a problem while using the application, please inform the development team.
