About this app
Need a formula during class, homework or exam revision? Formularium combines a clear, searchable mathematics reference with a practical study tool. Browse by topic, jump directly to a formula, save useful sections, or practice them as flashcards.
Learn, not just look up
Choose ready-made practice sets for algebra, analysis, linear algebra and trigonometry, or build your own set from the formulas you want to remember. Hundreds of flashcards turn key definitions, rules and identities into short practice sessions. A Leitner-style spaced-repetition system prioritizes new and due cards, tracks your progress and brings difficult material back sooner.
A broad formula reference
• Algebra: numbers, polynomials, exponents, roots, logarithms and summations
• Linear algebra: matrices, systems of equations and determinants
• Trigonometry: angles, triangles, values and identities
• Geometry: plane figures, solids and vectors
• Functions and analysis: limits, asymptotes, derivatives and integrals
• Complex numbers, descriptive statistics and combinatorics
• Physics: mechanics, waves, thermodynamics, optics, electricity and more
• Symbols, sets, mathematical constants and useful tables
Made for focused study
• Search formula titles and content
• Browse a structured table of contents
• Save frequently used sections as favorites
• Switch supported angle formulas between degrees and radians
• Read textbook-style mathematical notation and purpose-built diagrams
• Use the formula reference and practice features offline
• Study on phones, tablets and Chromebooks
Your favorites, selected practice sets and learning progress are stored on your device. No account is required.
Formularium is designed for secondary-school and university students, teachers, and anyone who wants a dependable mathematics reference close at hand.
