This app mimics the four most important technologies to detect paranormal activity. RADAR: A radar works by transmitting a signal through electromagnetic waves called radio waves. These waves bounce off certain types of distorted, unstable and abnormal signals. In other words, the radar will detect any irregular energy or fluctuations in the environment. EMF: An EMF detector finds electron vibrations in a given area. This is similar to a radio antenna. INFRASOUND & EVP: InfraSound is sound that is lower in frequency than 20 Hz, which is the normal limit of human hearing. Electronic voice phenomena (EVP) are sounds usually found in background noise from stray radio transmissions which sounds like static, but it can also pick up odd sounds. IONS: An Ion detector can detect positive and negative ions within an electric field. An ion is a positive charge. When there is high amounts of positive electromagnetic discharges it is thought to be due to paranormal activities. Disclaimer: This app is made for fun and entertainment purposes only.
