Discretica helps CS students learn discrete math with interactive calculators, proof practice, and 500+ guided problems you can study offline. Built for Discrete Structures and Discrete Mathematics courses, Discretica focuses on the topics that show up in homework, quizzes, midterms, and finals. What you can study: - Logic and propositions: connectives, truth tables, equivalences, and quantifiers - Proof methods: direct proof, contradiction, contrapositive, and induction - Sets, functions, and relations: set operations, Venn diagrams, properties, and mappings - Counting and combinatorics: permutations, combinations, pigeonhole, and binomial theorem - Graph theory and trees: paths, cycles, connectivity, BFS, DFS, and spanning trees - Boolean algebra: expressions, laws, logic gates, simplification, and circuits - Number theory: divisibility, primes, modular arithmetic, GCD, LCM, and Euclidean algorithm Interactive tools: - Truth Table Builder for logical expressions with AND, OR, NOT, implication, biconditional, and XOR - Set Operations with union, intersection, difference, symmetric difference, cardinality, power sets, and Venn visuals - Combinatorics Calculator for permutations, combinations, factorials, and stars-and-bars - Modular Arithmetic for addition, subtraction, multiplication, powers, and inverses - Base Converter for binary, octal, decimal, and hexadecimal - GCD and LCM Calculator with Euclidean and extended Euclidean steps - Proof Trainer with fill-in-the-gap, reorder-the-proof, and choose-the-method exercises Practice that actually helps: - 500+ bundled practice problems across beginner, intermediate, and advanced levels - Hints, explanations, and step-by-step solutions - 30 rotating daily challenge problems - Mistake notebook with spaced review - Progress tracking with streaks, levels, topic mastery, and achievements - 54 formula and reference cards across the core syllabus Free to start: Use four free calculators, read the first subtopic in every module, complete daily challenges, and practice up to 8 problems per day. Discretica Premium unlocks all lessons, all tools, unlimited practice, step-by-step solutions, the full mistake notebook, and the proof trainer.

Verdict
The clearest difference is in-app purchases: Lie group at none against Discrete Math's 3. Discrete Math's advantage is device support. On price and iOS requirement there is nothing between them.
