Most mobile phones contain an internal sensor to measure magnetic fields. This sensor is used to calculate the position of your phone.

Our application analyzes the changes in the magnetic field. This sensor works with the phone itself and with most Android devices. Our sensor is optimized for Android to provide you with the best results.

By default, the application detects metallic items in front of your device. You can modify it to detect all the items.

We use a graph to analyze the magnetic field values.

You can adjust the sensitivity of the detector and also the time interval of the analysis.
