Cognitive Age Check
Read full descriptionHide full description
Cognitive Age Check turns brain training into a quick, game-like daily habit. Take a 5–8 minute test built from rotating cognitive games — digit spans, sequence and grid memory, Stroop, reaction speed, odd-one-out patterns, analogies, rotation puzzles and more. You get a playful Cognitive Age estimate plus area scores for attention, memory, processing speed, pattern recognition, verbal reasoning and spatial skills, with a cautious app-user percentile. WHAT YOU GET • A Cognitive Age estimate compared with your real age • Six area scores + a consistency score • Your strongest area and a suggested focus area • A trend you can track over weeks, with simple charts • 5 quick 2–3 minute practice exercises • Short Learn cards on cognitive reserve, sleep, exercise and brain health FRESH EVERY TIME Tasks are pulled from a large rotating pool with light difficulty adaptation, so repeat tests feel new instead of memorized. PRIVATE BY DESIGN Everything stays on your device. No account, no sign-up, no tracking, and no medical data sent anywhere. Ads, if shown, are non-personalized. IMPORTANT — BRAIN FITNESS, NOT MEDICAL SCREENING This app provides general cognitive fitness and educational information only. It is NOT a medical device, NOT a dementia test, NOT an IQ test, and NOT a diagnostic tool. It does not diagnose, prevent, or treat any condition. One test is a snapshot, not a diagnosis. If you are worried about memory loss, confusion, personality changes, or daily functioning, please speak with a qualified healthcare professional.
