This is a joke app. [Pranker App] :)
If it exceeds 200Bq, you will hear amazing images and sounds.
Let it be used by those who want to be surprised.
* It goes up and down several times, so let's open it and give it to you a little later.
* A scream sounds at a volume ten times that of the first beep.
Please try the volume once before handing it over.


・ Do not use if you have heart disease.
・ For those who are sensitive to sound, please give it a small sound.



The concept is to detect ghosts.
It would be nice to use it in a place where a little ghost is likely to appear.
