Description by atsuko imai Written by the developer, not by AppBrain. Click to read.
Shapes stream across the screen — circles, triangles, squares, stars — in four directions and five colors. One rule: tap only the ones that match the prompt. Sounds simple. Gets real fast.
〔Four Ways to Play〕
· 10-Question Challenge — Four difficulty levels (Easy to Expert) plus negation prompts ("tap everything except…") keep every session fresh
· Daily Challenge — 10 questions shared worldwide each day. Track your streak and share results Wordle-style
· Endless Mode — Survive as long as you can. No mercy.
· 200 Levels — A long-form progression that grows with you
〔Brain Age〕
Your reaction speed is measured and converted into a brain-response age (15–80). Play daily to push it younger.
〔Built with care〕
· 80 prompt patterns (4 shapes × 5 colors × 4 directions)
· Detailed stats with Swift Charts
· Dark mode and color-accessibility support
· No internet required (except ads)
· Zero personal data collected
〔Privacy〕
All gameplay data stays on your device. No account needed.
