Store description excerpt
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
