About

Magnetometer・Magnetic Field

This app visualizes your phone's magnetic field sensor readings, showing deviations from a calibrated baseline. It features a live waveform, haptic feedback for peaks, and adjustable sensitivity for detailed analysis.

Highlights
  • Magnetic field deviation from baseline
  • Live waveform display
  • Haptic feedback for peaks
  • Adjustable sensitivity levels
  • Peak count and duration summaries
  • Calibration for local baseline

Magnetometer shows you the magnetic field your phone can already sense. Calibrate a local baseline, then watch how far the field moves away from it — live, in microtesla (µT). How it reads • The big number is deviation from your calibrated baseline in µT, not an absolute field value • An arc gauge moves through four states: Weak, Moderate, Strong and Peak • A rolling waveform shows how the field changed over the last few seconds • Raw X, Y and Z components are listed under the gauge in µT Peaks you can feel • A local peak — a rise followed by a fall — triggers a full-screen flash and haptic feedback • A beep repeats faster and gets louder as the signal gets stronger, so you can watch where the phone is instead of the screen Control the measurement • Calibration establishes your local baseline and rates it: Excellent, Good, Fair or Poor • Four sensitivity levels change how strongly the normalized signal is scaled • High Precision filters noise harder — stronger smoothing, a stricter peak threshold and a longer debounce. Fewer false peaks and a slightly slower response; it does not amplify the signal • Stop a scan yourself and it is saved as a summary: peak count, duration, mode and calibration quality. Up to 100 summaries stay on your device Where people use a magnetometer • Checking whether a screwdriver, scissors or a tool tip has become magnetised • Comparing how strong different fridge magnets, speaker magnets or clasps are • Seeing how the field around a running motor, speaker or appliance changes with distance • Finding out whether a phone case, wallet or stand contains a magnet • Physics homework and classroom demonstrations that need a live µT reading • Simply seeing what the magnetic sensor inside your phone actually reports What makes this magnetometer different Most apps show one absolute number and leave you guessing whether it is high. This one asks you to calibrate where you are standing first, then reports the deviation from that baseline — so the reading answers "how much did the field change here" instead of "what is the field somewhere on Earth". The waveform, the four strength states and the peak flash all describe the same measured signal, and the app is explicit about what it cannot tell you. Getting a clean reading • Calibrate away from metal, magnets and electronics • Move the phone slowly and steadily • Take off cases that contain metal or magnets • Recalibrate when you move to a different room or surface What this app does not do Magnetometer reports what the sensor reads. It cannot tell you what caused a reading, and it does not identify magnetic sources, objects, materials or where they are. It is not a stud finder, a wall scanner or a metal detector, and it makes no claim about anything behind a wall or any other surface. Readings depend on your device's magnetometer and on nearby interference — treat them as a relative guide, not as a professional measuring instrument or a structural inspection tool. Your measurement summaries stay on this device. Requires a device with a built-in magnetometer. Available in 33 languages. Some of the features described require a subscription.
