TruColor app for iPhone and iPad
TruColor is a free game that takes advantage of the Stroop effect to train your brain and improve your reaction time. When you see a color word, like “red”, written in a different text color, like blue, it interferes with your ability to identify what color the word refers to.
In TruColor, you get sixty seconds to tap the colors that correspond to what the displayed words mean, rather than their color.
See how high you can get!
