Do you want to scare your friends?

Do you want to scare your friends? The title of the apps says everything about it. And it is that your smartphone can be a good ally in your jokes.

The working of the app is very simple: we only have to choose one of the terrific images that they propose us, a scary sound and fix the time in which we want the joke to take place.

The idea is to give the mobile to a friend, telling him to try a game or to look for something in it. When he is really focused making what you have asked him to do, the program will launch with the image and the sound that you have chosen. It is a very simple concept, but at the same time it is very is it almost impossible that the victim does not get scared.

It is a variant of the classic joke of the labyrinth and the picture of the Exorcist's Child. It is just that in this case, you can choose the image as well as the sound and the scare is not associated to a suspicious game. You can ask your friend to look to your last picture uploaded in Facebook and the app will do the same.

But, be careful when using this kind of apps, as there are people who are too much sensitive or with heart problems. Also, if the scared friend throws the mobile through the window, then the shock will be yours!
