Description
Turn your phone into a pocket magnetometer.
This magnetometer reads the built-in magnetic sensor and shows the surrounding magnetic field strength in microtesla (μT). See X, Y, Z axis values and the total field at a glance, with a live mini chart so you can spot changes the moment they happen.
★ Three modes in one app • Measure — total field, per-axis values, live history graph • Metal Detector — set a baseline, get a vibration alert when nearby metal shifts the field • EMF — quick reading classified as Normal, Slightly High, or High based on the 25–65 μT Earth-field range
★ Useful for everyday checks • Find nails, screws, rebar or hidden wires before drilling into a wall • Test if a magnet, speaker, or motor is producing a strong field • Compare appliances near your bed, desk, or workspace • Verify if a "neodymium" magnet is actually strong • Curiosity, school science, geomagnetism class
★ Designed to stay out of your way • Clean Material 3 interface, light and dark theme • 13 interface languages • Measurement runs on-device • No account required
★ Important to know before using • Detects ferrous metals — iron, steel, nickel. Aluminum, copper, brass, gold typically do not register. • A magnetic phone case (MagSafe, magnetic mounts, wallet rings) sits right next to the sensor and will skew readings. Remove the case for accurate measurement. • Sensor accuracy varies by phone model. • This app is a reference tool. It is not a replacement for professional EMF meters or stud-finders used for safety, medical, or industrial work.
If your phone does not have a magnetic sensor, the app will tell you on launch.
Try Magnetometer the next time you want to know what the magnetic field around you actually looks like.
