A free program for Android, by AHK Developers.

This application will detect any type of paranormal activity with an advanced algorithm based on the latest EMF detection technology. The algorithm will detect all types of anomalies and translate them into digital signals that can be displayed on the user’s device.

You can also set up a trap to catch a ghost or other paranormal entity, and it will work like a real detector.

The user will get an alert whenever the algorithm detects a specific EMF value.

If you want to detect paranormal activity in a particular place, you can also set up a trap in which you can place a sensor that will measure the magnetic field strength.

That said, this is just a prank app, so the user should not take it seriously.
