## What is Math Zen?

Math Zen is a math practice app built for real exam performance, not a calculator that does your homework for you.

Work through algorithmically generated problems that cover the topics and skills tested on real exams. The adaptive mastery-based progression system tracks your accuracy and adjusts difficulty automatically: struggle with a concept, and it comes back for review; master it, and you advance. Practice offline, anytime, with zero distractions.

EXAM PREP

Math Zen includes exam-style problem sets for major standardized tests:

- AP Calculus AB: 30 templates: particle motion, optimization, related rates, FTC, and accumulation functions.
- SAT Math: 41 templates with word problems, real-world contexts, and data interpretation.
- Gaokao Mathematics: 43 templates in formal Chinese math style.
- A-Level Maths: Pure and Statistics, covering calculus, trigonometry, vectors, probability and hypothesis testing. Mechanics is not covered.
- Also available: AP Calculus BC, Suneung, Abitur, Kyōtsū Tesuto, Baccalauréat, Selectividad, EXANI-II, ENEM and GSAT exam paths.

Exam prep problems include multi-part questions, where each part builds on the one before it.

24 TOPICS, 570+ PROBLEM TEMPLATES

Six sections covering math from arithmetic through university-level content:

Algebra: Arithmetic, Algebra, Complex Numbers, Logarithms
Precalculus: Functions, Graph Analysis, Hyperbolic Functions, Sequences & Series
Calculus: Limits, Derivatives, Integrals, Differential Equations, Partial Derivatives, Parametric Equations, Polar Coordinates, Multiple Integrals, Laplace Transforms
Geometry & Trigonometry: Geometry, Trigonometry
Linear Algebra: Vectors, Matrices, Abstract Algebra
Discrete Math: Probability, Statistics

156 subtopics. 570+ algorithmically generated templates. Every session is different.

KEY FEATURES

Mastery-Based Progression: A five-level bucket system tracks your accuracy within each subtopic and advances you from easy to hard as you demonstrate understanding. Structured, adaptive practice, not random drilling.

Theory Built In: Every subtopic carries the rules its own problems need, with worked examples. Tap Show the rule the moment an answer comes out wrong, or open it from the header mid-problem.

Mistake Journal: Every wrong answer is captured automatically. Come back later and retry that exact problem type with fresh numbers, until the concept clicks. Resolve them all for a small celebration.

Visual Problems: Interactive graphs, geometric diagrams, and animated transformations bring abstract concepts to life.

Leaderboard: See how your practice volume compares to other students.

Offline First: The whole app works without internet. Practice on a plane or subway; progress syncs when you reconnect.

Dark Mode: Follows your system setting, or pin it to light or dark.

No Ads, Ever: Clean, focused, distraction-free. No ads, no coins, no lives.

11 Languages: English, Russian, Chinese (Simplified and Traditional), Japanese, Korean, German, French, Spanish, Portuguese, Swedish, Dutch.

PERFECT FOR

- Students preparing for AP Calculus AB/BC, SAT Math, ACT Math, or IB Math
- Students preparing for Gaokao, Suneung, Kyōtsū Tesuto, or Abitur
- University students in Calculus I/II, Linear Algebra, or Differential Equations
- Self-learners who want structured math practice at their own pace

HOW IT WORKS

1. Choose a topic or an exam prep path.
2. Math Zen generates a fresh problem (a quick quiz of one concept) matched to your current level.
3. Solve it: type your answer or select multiple choice.
4. Right answers advance you. Wrong ones show the rule and go to your mistake journal.

Love this app such an amazing way to avoid doomscrolling

**Developer response:** Thank you soo much for review!

### 5/5 — Awesome app!

*2026-04-17*

I’m addicted, such a great way to keep brain working. Never have I thought that I would be solving maths on a daily basis on my phone. Had a minor problem which was fixed same day as I contacted the developer. Thanks for the app!

**Developer response:** Hey, thank you!

## Version history (last 5 releases)

### 1.22.4 — 2026-08-31

Math problems now fit compact screens more cleanly. We improved line wrapping so formulas, fractions, roots, and grouped expressions stay together instead of breaking in awkward places.

### 1.22.1 — 2026-08-28

A scratchpad, on the problem screen.

Tap the pencil and a working area opens under the problem. Do the arithmetic where you can still see the question. On expression problems it lends you the same keypad you answer with, and it wipes itself when the next problem loads.

Also fixed from your reports: change-of-base questions printed as raw source, and a cubic that rejected its own second root.

### 1.21.0 — 2026-08-26

Math Zen now speaks Swedish and Dutch: 11 languages in total.

Two new exam paths to match: Högskoleprovet (the Swedish university admission test, quantitative part) and VWO Wiskunde (the Dutch pre-university maths exam).

Also fixed formula rendering in a handful of problems, including z-test decisions and sin(ax)/ax limits.

### 1.20.2 — 2026-08-20

The value was right, the notation was not: a polar-area problem could write its answer as "502π" when it meant 50 · 2π. Fixed.

Dark mode no longer flashes light card backgrounds on a cold launch.

Plus monetization adjustments in some regions.

### 1.20.1 — 2026-08-18

The working, not just the answer.

Every tangent line problem had a broken solution. The last step restated itself: the tangent to f(x) = 2x² + 4x + 3 at x = -1 was worked as "y = 0(x - -1) + 1 = y=1". The answer was right the whole time, the reasoning printed underneath it was not. A negative point no longer prints as a double minus either, and a term of zero no longer prints at all.

Factoring with a leading coefficient could hand back an answer that still had a factor left in it. "3x² + 12x + 9" came back as "(3x+3)(x+3)" instead of "3(x+1)(x+3)", on the exercise whose whole point is pulling the common factor out.

And a logarithm problem on the product property could set the same term twice, "log₄(8) + log₄(8)", which reads as a typo rather than a property worth using.

All three came from reports sent from inside the app. They get read. Keep sending them.
