About 電磁波チェッカー
Measure the magnetic field around you with your phone's magnetometer.
Every iPhone has a magnetometer for its compass. EMF Checker reads the three-axis magnetic field and shows its strength in microtesla (µT). It picks up the low-frequency magnetic fields made by microwaves, transformers, wiring, speakers, motors, and magnets.
Features
- Analog-meter face with a glowing LCD readout
- Calibrate to set your current spot as the baseline
- Delta from baseline and a 5-level color danger scale
- Click and haptic feedback on magnetic spikes
- Raw X / Y / Z axis values
How to use
Tap Start, then Calibrate to set the baseline, then move the phone toward whatever you want to check.
Important
This is a magnetic-field meter, not an RF/EMF meter. It cannot measure WiFi, 5G, or microwave RF. Sensitivity and accuracy vary by device, and readings must not be used for medical, safety, or emergency decisions. It is for reference, experiments, and fun. No data is collected or transmitted.
