What is a ghost? We all have encountered spirits at some point in our life. Many people believe that these spirits remain after death and come back to live in the world of the living. This is a very common belief, but there is no scientific evidence to support this idea.
Spirit Radar - Ghosts Finder is a free app for Android devices that uses the embedded sensors to detect disturbances in the electromagnetic field. This app can be used as a ghost detector. The sensors on your phone or tablet are used to detect ghosts and spirits.
The app uses the FFT (Fast Fourier Transform) and DFT (Discrete Fourier Transform) algorithms to detect the most relevant frequencies in the signals.
