Stroopium app for iPhone and iPad

Stroopium is a "game" implementation of the Stroop Effect. It tries to facilitate the process by implementing the way of playing: you can touch or you can talk.
The Stroop effect is a demonstration of interference in the reaction time of a task. When the name of a color is printed in a color that is not denoted by the naming the color of the word takes longer and is more prone to errors than when the color of the ink matches the name of the color. You can try this game against the clock, for a limited amount of times or limitless until you get one wrong.
