Math Zen vs Calculus

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. AP PRECALCULUS, AP CALCULUS, SAT AND ACT MATH PREP Math Zen has dedicated exam paths for the tests US students actually take: • AP Precalculus: polynomial, rational, exponential, log and trig functions, plus rates of change from tables and graphs. • AP Calculus AB: particle motion, optimization, related rates, the Fundamental Theorem of Calculus, accumulation functions, and free-response questions with linked parts. • AP Calculus BC: everything in AB plus series, parametric equations, and polar coordinates. • SAT Math: 40 SAT-style templates across Algebra, Advanced Math, Problem-Solving and Data Analysis, and Geometry and Trigonometry, with word problems, data and charts. • ACT Math: algebra, functions, geometry, trigonometry and statistics, from radical equations to circles, two-way tables and charts. Exam prep problems follow each test's format: multi-part questions where each part builds on the last, Kyōtsū Test digit boxes, Suneung short answers, and five-option ENEM questions. Also included: IB Math AA, Hong Kong DSE (Compulsory, M1, M2), A-Level Maths, Taiwan GSAT and AST Math A, Gaokao, Suneung, Kyōtsū Test, Abitur, Baccalauréat, Selectividad, EXANI-II, ENEM, FUVEST, VWO Wiskunde, Högskoleprovet, and Polish Matura paths. 24 TOPICS, 870+ 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 238 subtopics. 870+ 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. 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. Visual Problems: Interactive graphs, geometric diagrams, and animated transformations. 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. 12 Languages: English, Russian, Chinese (Simplified and Traditional), Japanese, Korean, German, French, Spanish, Portuguese, Swedish, Dutch, Polish. PERFECT FOR • Students preparing for AP Calculus AB/BC, SAT Math, ACT Math, or IB Math • High school students in Algebra 2, Precalculus, or Calculus • University students in Calculus I/II, Linear Algebra, or Differential Equations • Self-learners who want structured math practice at their own pace 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.

Calculus you can see is calculus you can learn. Calculus: Learn & Practice turns a full first-year calculus course into one clear path: build intuition with an interactive animation, follow a worked example step by step, then prove to yourself you've got it with instantly graded practice. WHAT'S INSIDE • 108 interactive concept animations — play, scrub and watch the key change happen instead of imagining it • 327 worked examples with complete solutions, visual hints and the mistakes students usually make • 1,215 practice problems graded the moment you submit, each with a full solution • Math-history stories with the original problems: Zeno's paradoxes, Archimedes' π, Fermat and Descartes' fight over tangents • Mistake tracking and mastery per concept, so you know exactly what to review • Spaced review that brings a topic back right before you'd forget it • Study Desk: a 2-minute micro-experiment every day, a Lab Notebook for your own conjectures, and a library of 219 counterexamples • A searchable library of 12 chapters, filterable by topic, tag and difficulty TOPICS COVERED • Limits and continuity • Derivatives and differentials • Applications of derivatives — optimization, related rates, MVT, curve sketching, L'Hôpital's rule, Taylor polynomials • Integrals — FTC, substitution, integration by parts, partial fractions, improper integrals • Applications of integration — area, volume, arc length, work • Differential equations • Infinite series — convergence tests, power series, Taylor and Fourier series • Multivariable differential calculus — partial derivatives, gradient, tangent planes, Lagrange multipliers • Vectors and 3D analytic geometry • Multiple integrals — double and triple integrals, cylindrical and spherical coordinates • Line and surface integrals — Green's, divergence and Stokes' theorems Great for Calculus I, II and III, AP Calculus AB/BC review, and exam prep. TRY IT FIRST Chapter 1 is completely free — animations, examples and practice all work, no time limit and no account. To unlock every chapter, choose Calculus Pro: a monthly or yearly auto-renewable subscription (the yearly plan may include a free trial for eligible users), or a one-time lifetime purchase. No ads.
