Midnight troll

Choose a sound effect, adjust the light threshold and hide your phone or tablet upon the wardrobe, or under the bed, or behind the TV on your victim's room.

Wait until they turn off the lights. After a random time between 5 to 15 minutes, an annoying or scaring sound will start.

When they turn on the lights to search for the origin of the sound, it will cease immediately without any trace.

And when the lights are turned off, the app will wait for a new period of 5 to 15 minutes and then start the sound effect again.

It will be a long, long night : )

Have lots of fun making those whom you love have an unbearably miserable night.

Midnight Troll comes with 4 free sound effects:
* Cricket
* Mosquito
* Dripping faucet
* Dog barking

And you can also buy new sound effects like:

(We are not responsible for your phone nor medical care if your victims decide to throw your phone in your head when they discover the prank ; )

*Note: the device must have a decent light sensor. Some cheap phones and tablets do not. Always test the app before buying addicional sound effects.
