Help Quantum Kate to discover subatomic particles and become a true Quantum Rascal! From Kate's room, you can access the portal to the quantum world and start the game. Coloured particles called quarks will pop up into your room. Connect two or three quarks together by drawing strings between them with your phone and form new particles - but be careful not to cross the strings! The more particles you discover, the more quarks you unlock. Watch out for the quantum particles you created: they are unstable and will decay into more quarks. Find all the particles you discovered in the highscore poster back in Kate's room. Play to beat your best score and discover all the subatomic particles to become a true Quantum Rascal!

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, SAT, ACT, GRE AND GMAT 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 all four content domains, with word problems, data and charts. • ACT Math: algebra, functions, geometry, trigonometry and statistics, from radical equations to circles, two-way tables and charts. • AP Statistics: sampling distributions, confidence intervals, z and t tests, chi-square and regression. 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: GRE Quantitative, GMAT Focus Quant, 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. 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, AP Statistics, 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.
