Ghost Detector Radar is a free app designed for Android devices that claims to detect and show spirits using the phone camera and different EMF and EMV. The app can be used as a ghost tracker and communicator, and it displays the spirit power on the camera image. The higher the power, the closer the ghosts are. The app also features a flashlight to help you find ghosts in the dark.

The app has a radar feature that displays a green dot if there is a nearby source of magnetic emission. It also has an EVP chart and a ghost camera. The app can be used to simulate hunting spirits and remove phasmophobia in people. The detection range varies between 0 and 30 feet approximately, depending on the mobile device used.

However, it is important to note that this app is a prank app and will not actually detect ghosts. The app uses the different sensors of the device, so it depends largely on the precision and quality of the terminal. Since paranormal activity can't be scientifically proven, the results of this app cannot be scientifically verified. Use this app at your own risk.
