## What is Number Gym?

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.

## Version history (last 5 releases)

### 1.4.0 — 2026-08-25

Home now opens with the Daily Workout: three games picked for you each day, one from each category, and a single button to start. Play them in any order — the results screen points you to the next one. Next to it, Gym Score sums up your level across all games as a single number from 0 to 100, along with how it moved over the past week.

New players get a real start: a short welcome, a trial round that sets your starting level, and a "first steps" checklist on your profile. Choosing difficulty is clearer too — three named tiers instead of two options: Novice, Regular, Advanced.

On iOS you can keep your Daily Challenge streak on the Home Screen or Lock Screen with the new widgets. Premium no longer requires an account, four new avatar frames joined the collection, and the app has a new icon.

Under the hood: a broad performance pass — faster launch, smoother games and results, lighter sync. Your Daily Challenge history now comes back from the server after a reinstall, plus plenty of smaller fixes throughout.

### 1.3.0 — 2026-07-14

Achievements got a major upgrade: tiered badges, new goals for the Daily Challenge and courses, a progress bar toward each one, and a showcase on your profile. Everything you've already earned unlocks retroactively.
We also redesigned the results screen around your personal bests and gave the app a fresh icon and launch screen.
On the Daily Challenge, the global leaderboard now shows the top 20 with your own spot highlighted, and every league has its own board. Rating changes are gentler, Eagle Eye gets tougher at the top levels, and there's plenty of smaller polish throughout.

### 1.2.1 — 2026-06-23

We refreshed the icons throughout the app and made switching between tabs instant. Course progress now syncs across your devices, and we fixed a crash in lessons and some navigation — plus lots of small fixes.

### 1.2.0 — 2026-06-16

Two new games:
• Mental Rotation — read and match rotated numbers and figures, from gentle tilts to tricky mirrored shapes.
• Eagle Eye — keep your eyes on the center and catch numbers flashing at the edge of your vision.

New Premium perks:
• Time Machine — go back and play Daily Challenges you missed in the past week, with full streak credit
• Streak freezes — up to 2 missed days a month no longer break your streaks
• Avatar frames — 10 styles your friends see on leaderboards, in the arena, and in chat

Also in this update:
• A refreshed look — liquid glass across the app: tab bar, headers, and buttons, plus deeper cards. Light is now the default theme
• The rules of every game now open right from its card
• All 10 courses revised lesson by lesson; column arithmetic input now follows the written method
• Many small fixes and polish

Thanks for playing. Feedback is welcome at support@numbergym.app.

### 1.0.1 — 2026-05-29

• Speed Math: smoother progression for powers and roots
  • Number Reflex: retuned timing in Cascade and Dual Track
  • Daily Challenge: refined Grandmaster thresholds
  • Reminders: fewer repeats, fixed a stale evening notification
