Monster Defense Simulation

Simulated monster repellent to take your friends & childen the fear of monsters.

The Monster Defence 👾 is an exclusive app for Android, which proposes to flight these frightening figures with a simulated ultrasonic tone.

Of course there are no monster in reality, so this simulation is intended purely for entertainment. Use it to prank of your friends, or to take your children the fear of evil monsters under their bed.

Tell them that you can defense them by sonic. The generated are near the frequencies range, but be aware that your smartphone or tablet can not play real ultrasonic sounds. It is technically not possible with regular devices. Also, that there are no real monsters. ;-)

Please always activate the defense only briefly, because the generated pulses can be particular considered unpleasant of children. Adults can not hear some sounds. This is because the hearing loss in age.

If you like this app, I'd appreciate a positive review in the Google Play Store. Especially when you have taken your children or friends the fear of monsters under the bed. Please consider that this is explicitly is a fun app (prank) and that finally there are no real monsters. Not even in the closets of our children. ;-)

Bugs and feature requests can be communicated via email. I'll take care of it as soon as possible.
