What it is
Cold Spot turns your phone into a 60-second ambient session. Hold it still, listen to the room, and watch the gauge react to subtle changes in motion, magnetic field, and sound.
When something shifts, words rise. When the room goes quiet, it settles. Then you get a recap you can share.
It's not a real ghost detector — there's no such thing. What it is: a beautiful, well-made instrument for a fun moment with friends, a quiet room at night, or a Halloween party.
