Guys your not going to find a ghost using these apps you are simply going to find what frequencies are around you and it's not really important unless you are worried about radiation or harmful electrical currents or even weaponry such as directed energy that is ever increasing as a phenomenon. You can also detect things such as hidden devices , metals, coins, cameras whatever. Don't see some strange frequencies and believe you are ghost hunting most likely you found copper or something exceedingly conductive. If you don't get the same readings in the same places than it doesn't work
