心霊センサー関東の心霊スポット is a free Android app developed by Clairvoyance Ltd. It allows users to detect supernatural entities that are invisible to the naked eye using three unique algorithms: spiritual sensitivity, clairvoyance, and sound wave analysis. By determining the distance between the user and the spirits, the app categorizes them as safe, cautionary, or dangerous, with a total of 27 possible combinations.

The app also features a compilation of famous haunted locations that have gained attention online. With the help of the supernatural sensor, users can visit these haunted spots and experience them firsthand. However, it is important to note that visiting these locations is done at one's own risk.

Please be aware that the app holds no responsibility for any physical discomfort, spiritual possession, or any other adverse effects that may occur to the user, their surroundings, family, or loved ones after visiting these haunted locations. Use the app responsibly and proceed with caution.
