In the digital era, the utilization of technology in the field of education has provided new opportunities to develop more interactive and exciting learning methods. This research aims to show the effectiveness of using android applications in measuring magnetic fields as physics learning media. This research was conducted using a quantitative approach and pure experimental method carried out at the Physics Science Laboratory of FKIP Untirta by comparing the results of direct magnetic field measurements and magnetic field measurements using android applications (Gauss Meter Keuwlsoft, Magnetometer, and Physics Toolbox Magnetometer). The results showed that there is effectiveness in using android applications as learning media in measuring magnetic fields in physics learning. This is evidenced in the results of data processing that are close to the results of direct measurement, where the farther the compass distance, the smaller the angle of deviation of the compass needle, indicating the more minor the magnetic field in that position. Android applications can be an effective learning environment for learning physics, one of which is about magnetic fields. This research has important implications for the integration of technology in education.
