Math Zen vs Mathio

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. SUBSCRIPTION Math Zen is free to start with access to core topics. Premium unlocks the full topic library, all exam prep paths, and detailed analytics.
