Stroop Challenge Go vs Color Hunter

Stroop Challenge is a precision cognitive training tool based on the Stroop Effect — one of the most replicated findings in experimental psychology — measuring interference between word reading and color recognition. THE SCIENCE: The Stroop Effect demonstrates that automatic processing (word reading) can interfere with controlled processing (color identification). Regular exposure to Stroop-type stimuli has been associated with improved selective attention, cognitive flexibility, and processing speed. TWO VALIDATED MODES: • Classic (Color-Naming) — Identify the ink color of the presented word. Suppresses automatic reading response. • Word Match (Word-Reading) — Identify the color named by the word. Tests semantic processing independence. METRICS TRACKED: • Score per round (accuracy × speed composite) • Best accuracy rate (percentage of correct responses) • Fastest average reaction time (milliseconds per response) • Session totals: rounds played, correct and incorrect responses • Combo chains: consecutive correct responses DIFFICULTY SCALING: • Easy: 4 color stimuli (Red, Blue, Green, Yellow) • Medium: 5 color stimuli (adds Purple) • Hard: 6 color stimuli (adds Orange) DATA PRIVACY: All data is stored locally via UserDefaults. No network requests are made. No personal information is collected, transmitted, or shared. The app functions completely offline. Ideal for daily cognitive warm-up, focus training, or simply exploring one of psychology's most fascinating phenomena.

Color Hunter is a brain-training reaction game built on the classic Stroop Effect: every word is printed in a color that does NOT match what it says — "Blue" might be red, "Green" might be yellow. To win, you have to trust your eyes and ignore the word! ■ Dead-simple to play Every cell starts white with a color word on it. A voice calls out a color — tap the cell whose ink color matches it (go by the color, not the word). A correct tap fills that white cell with the color and locks it with a green outline. Match the whole board to win. ■ Fast and thrilling - Live timer down to the second - Only three lives — a wrong tap (ink color ≠ the spoken color) costs one, three mistakes ends the game - Word and color fight each other — the more you rush, the easier you slip. Seriously brain-bending. ■ Four difficulties for everyone Beginner, Easy, Normal and Hard — more cells means a harder hunt. Easy modes have big, friendly cells; Hard floods the screen with interference to test your focus and impulse control. ■ Thoughtful touches - Bilingual interface (English / 中文), auto-selected by device language - Spoken color callouts to play by ear and eye - Cloud leaderboard to see whose brain resists the trick best - Soft background music with a one-tap toggle - Pinch to zoom and pan, so even small cells stay readable Great for training focus, reaction time and cognitive flexibility — fun for all ages, anytime, anywhere!
