Train your brain in just 2 minutes a day.
ColorBrain uses scientifically validated neuropsychological tests — the Stroop Test and Eriksen Flanker Task — to sharpen your attention, boost reaction speed, and strengthen cognitive control.
HOW IT WORKS
▸ Color Mode (Stroop Test): See a word, tap the color the text is written in — not the meaning. Red text spelling "BLUE"? Tap red. Easy to understand, hard to master.
▸ Direction Mode (Flanker Task): Tap the direction of the center arrow while ignoring the flanking distractors. Focus is everything.
WHY IT WORKS
These are gold-standard tests used by neuroscientists worldwide. Regular practice builds selective attention, cognitive flexibility, and mental processing speed.
ADAPTIVE DIFFICULTY
ColorBrain watches your performance in real time. Accuracy above 85%? It pushes you harder. Struggling? It eases back. You're always in the optimal learning zone.

JUST 2 MINUTES A DAY
