About Number Gym: Brain Training
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. Open Number Gym and start with today's challenge.

What’s new
Version 1.5.0 · Updated August 29, 2026
Milestones in the activity feed can now be liked. When someone you follow unlocks an achievement, finishes a lesson or a course, or posts a Daily Challenge result, you can back it with one tap — a single like per person, and tapping again takes it back. Ordinary rounds carry no like; they happen too often to mean anything. When your own milestone gets liked, the Friends tab shows a dot, and likes that arrive together come as one notification instead of one per tap. The Stats screen now opens with Your Activity — your own milestones in one list, with the likes they collected. Gym Score has a history now. The analytics screen adds a trend chart of your overall level over the last 30 days or weeks, next to the score and its change for the week. You can also see other players' Gym Score — in the arena ranking, on suggested rivals, and as a full breakdown by category on their profile. Reviewing a missed question on the results screen now shows the real prompt and the real answer in every game: grids, figures and rings are drawn instead of described. Target Sum never repeats a tile, and fractions get their proper share of a round. Chat recovers messages that arrived while the connection was down, home cards line up with the game grid on tablets, and the Mint theme reads clearer.
