Number Gym: Brain Training
Math, memory & logic games
Free · In‑App Purchases · Designed for iPad
Two new games — Mental Rotation and Eagle Eye. Plus a liquid-glass look and new Premium perks: streak freezes and a Time Machine for missed Daily Challenges.
Train mental math, memory, and logic in five focused minutes a day. 21 short games that meet you at your level and grow as you do. No ads, no tracking, no streaks shaming you — just a calm daily practice for a sharper mind.
THREE CATEGORIES, 21 GAMES
• Arithmetic — 9 games for mental calculation: addition, multiplication, equations, missing numbers, fractions, percentages.
• Memory & attention — 5 games to recall numbers, sequences, positions, and visual patterns — and to catch numbers at the edge of your vision.
• Logic — 7 games for reasoning, pattern recognition, logic circuits, and rotating shapes in your head.
ADAPTIVE DIFFICULTY
Every game tunes itself to you. Each has its own rating from 0 to 100 — as you improve, questions get harder; when you struggle, they soften. You always play near your edge: never bored, rarely frustrated.
DAILY CHALLENGE
A new set of 30 questions every day, the same for everyone worldwide. Compare on the global leaderboard or among friends, and build a streak for consistent practice.
CALM BY DESIGN
No ads. No tracking across other apps. No shaming streaks, no flashing rewards, no addictive loops. Number Gym respects your attention — it's built to be put down, not to keep you hooked.
COURSES WITH CERTIFICATES
Structured lessons from basics to advanced — mental multiplication, fast addition, percentage tricks. Pass the final exam, earn a certificate, share it.
FRIENDS & ARENA
Add friends, follow their progress, and challenge them head-to-head. The weekly Arena ranks the most active players worldwide.
PREMIUM
Unlock the full game collection, all courses, and unlimited statistics — plus streak freezes, a Time Machine for missed Daily Challenges, and avatar frames. Monthly, annual, or lifetime plans.
ALSO
80+ achievements to mark your progress. Fully localized in 20 languages, including right-to-left Arabic.
PRIVACY
We collect only what the app needs to work — your email, name, and game results. Nothing sold, nothing tracked across other apps.
