This app turns your smart phone into a Ghost detector. Unlike the most apps on the market that use Electromagnetic fields for searching for ghosts (which is very inaccurate and will give you random results), Ghost sensor searches for so called "Cold Spots".
Cold spot describes an area of localized coldness or a sudden decrease in ambient temperature that is allegedly connected to paranormal activity. As soon as Ghost Sensor adapts to the room temperature you can start your hunt.
Please note that the accuracy of this app depends on the accuracy of your devices sensors!
