About

Two minutes a day for sharper attention and faster reactions. ColorBrain turns four classic attention tests into quick daily training. Every session adapts to you, and every result shows you something about how your attention works. FOUR WAYS TO TRAIN ▸ Color — the Stroop test. "GREEN" printed in red? Tap red. Your brain wants to read the word; you train it to look at the ink. ▸ Direction — follow the arrow while the word under it and the arrows around it point the other way. ▸ Impulse — a go/no-go test: tap on green, hold back on everything else. ▸ Numbers — a Schulte table: find the numbers in order as fast as you can. DAILY CHALLENGE One 60-second challenge a day, the same for every player. See where you place among today's players on the Game Center leaderboard. SEE HOW YOUR ATTENTION WORKS After every session: accuracy, reaction time and your distraction cost — how much slower you answer when what you read conflicts with what you see. Watch it shrink as you practice. ADAPTS TO YOU Difficulty rises when you are accurate and eases off when you struggle, so every session stays challenging but doable. BUILD THE HABIT A daily streak, a home-screen widget and a reminder at the time you choose. PREMIUM • All four modes, including Numbers • Unlimited training every day • Your full history and trends • Distraction cost and self-control insights for every mode • Streak freeze: miss a day without losing your streak Free: 3 sessions a day, the Daily Challenge and your last 7 days of stats. No ads. ColorBrain is a training game, not a medical or diagnostic tool.
