About

Number Memory

Features
Read full description

How sharp is your brain? Number Memory puts your working memory and reaction speed to the test — then gives you a Brain Age score that tells you exactly where you stand. HOW IT WORKS Two modes. One goal: find out what your brain is actually capable of. • NUMBER MEMORY Numbered circles flash onto the screen in random positions. Study them. When they vanish, tap them back in order — 1, 2, 3 — purely from memory. Nail every round and a new circle gets added. One wrong tap ends the game. Your Brain Age is calculated from the level you reached, your accuracy, and how quickly you tapped. • REACTION TIME Five rounds. The screen flashes green — tap as fast as you can. Your average response time is recorded in milliseconds and your personal best is saved automatically. YOUR BRAIN AGE SCORE An algorithm combines your level, accuracy, and tap speed into a single Brain Age number, paired with a label: Legendary · Master · Expert · Great · Average · Almost · Keep Going · Try Again. The score is a fun, motivating benchmark — chase it every session. TRACK YOUR PROGRESS - Best level ever reached - Best Brain Age score - Current streak counter - Bar chart of your last N games - Recent game history at a glance SHARE YOUR RESULT Your result card is shareable directly from the result screen — challenge anyone you like. REMOVE ADS A single one-time purchase removes banner, interstitial, and rewarded ads permanently. Second-chance and hint features stay free for everyone. PRIVATE BY DESIGN No account. No sign-up. No server. All data stays on your device and the app works fully offline. WHAT SCORES LOOK LIKE IN PRACTICE Beginners typically reach level 4–5. Average players land around 6–8. People with strong working memory often hit level 10–12 or beyond. Where will you fall? FEATURES AT A GLANCE • Two brain-training modes: Number Memory + Reaction Time • Brain Age score with 8 performance labels • Personal-best tracking and streak counter • Bar chart history of recent sessions • Shareable result card • One-time Remove Ads purchase • No account required — works 100% offline • All data stored locally on device For entertainment only — not a medical assessment.
