EMF stands for Electromagnetic-Field. This app uses the magnetic sensor (compass) of your phone and displays the reading in graphs as well as in meter format.
After installing app you just need to open any format for measuring magnetic field and it will automatically start reading magnetic field. It also lets you detect magnetic field of different devices and objects around you so you can also test out different things.

You can use this app to measure and study magnetism and electromagnetism, the earth’s geomagnetic field and more. It can be used as a detector not only for EMF but also for magnets, metals, devices and spy cameras too.

This app provides accurate results of electromagnetic fields around you so you don’t need to buy any kits for detecting magnetic field. You can use this app free of cost.

You can find any lost magnets or devices that contains magnetic field using this app too.

Features:
Display Electromagnetic-Field in form of meter format.
Display Electromagnetic-Field in form of digital meter.
You can save it and use it for studies in future too.

Note: If your phone don’t have magnetic sensor then it will not work.
