About BRAIN!

BRAIN! is an app that helps you evaluate and track your brain’s condition. When you’re struggling to concentrate or feeling mentally foggy, BRAIN! allows you to quantify your cognitive state. It measures four key indicators: ・Focus (SART) ・Cognitive control (Stroop task) ・Working memory (n-back task) ・Processing speed (TMT) Easy to use — each test takes less than 5 minutes. Your scores are automatically saved and visualized in graphs to track changes over time. Ideal for checking your mental condition before and after work or study, or monitoring the effects of sleep and nutrition. Also great for peak performance and recovery planning. Your brain deserves conditioning, too. Start visualizing your cognitive power with BRAIN!
