EMF Detector: Magnetic Meter

EMF Detector: Magnetic Meter turns your phone into a simple magnetic

field meter. Open the app, point your phone, and see live EMF readings

from the built-in magnetometer sensor.

WHAT IT DOES

- Live magnetic field readings in microtesla (µT) and gauss

- Real-time graph so you can watch levels rise and fall

- Peak and average value tracking during a scan

- Detects the strength of magnetic fields near appliances, wiring,

speakers, motors, magnets and metal objects

- Works offline — no internet needed to take a reading

HOW TO USE IT

1. Open the app and hold your phone flat.

2. Walk slowly toward the object you want to check.

3. Watch the reading climb as you get closer to the source.

4. Compare readings in different rooms to find the strongest spots.

WHERE PEOPLE USE IT

- Checking magnetic field levels near a router, TV, fridge or microwave

- Finding hidden wiring, pipes, studs and metal behind walls

- Testing whether a magnet or speaker is still working

- School and college physics experiments

- Hobby ghost hunting and EMF exploration

- General curiosity about the electromagnetic environment at home

WHAT YOU SHOULD KNOW

This app reads your phone's magnetometer, the same sensor the compass

uses. It measures magnetic field strength only.

It does NOT detect nuclear radiation, ionizing radiation, gamma rays,

X-rays or radioactivity. It is not a Geiger counter and cannot replace

one. It also does not measure radio frequency (RF) or Wi-Fi signal

power directly.

Readings are limited by your phone's hardware. Different phones have

different sensor quality, so values are useful for comparison and

exploration, not for professional, medical or safety measurements. Do

not rely on this app for any health, safety or compliance decision. For

that, use a certified EMF meter and consult a qualified professional.

If your readings look wrong, calibrate the sensor by moving your phone

in a figure-8 pattern a few times, and move away from magnets, cases

with metal clips, and wireless chargers.

REQUIREMENTS

Your device must have a magnetometer sensor. Most Android phones do. If

the app shows no reading at all, your device likely does not include

this sensor.

The app is free and supported by ads.
