Pro Ghost Detector is a free Android app developed by HyperAppStudio that uses sensors in your mobile device to detect sources of variable magnetic emissions. The app is designed to detect magnetic fields that are not at constant frequencies, such as those generated by paranormal activity, and will show a green dot on the radar if there is a source of magnetic emission nearby. However, it will not detect magnetic fields generated by electronics like TV, routers, computers, chargers, and mobile phones. The detection range of the app varies between 0 and 30 feet approximately, depending on the mobile device used.

If you are interested in paranormal activity and want to detect it using your mobile device, Pro Ghost Detector could be the perfect app for you. The app is simple to use and provides a unique way to detect any paranormal activity that may be occurring around you. Keep in mind that this app is for entertainment purposes only and should not be used as a substitute for professional equipment or advice.
