It is an application that simulates a test of reflexes. Which asks us to press a few points on the screen and when we are focused by pressing points, mobile vibrates, it emits a screech and screen a scary image is displayed. The shock is assured.

Before giving the start button make sure the phone volume is at maximum.

Do not use with people with heart problems.

Once the application is installed on both the icon and the title it does not show anything that is no joke to scare the victim not wait.
