Math isn't only problem-solving. Every problem you solve leans on things you have to remember: formulas, identities, definitions and the steps of a method.
Space Repeat lets you write them in real math notation, so a fraction looks like a fraction and an integral like an integral, and brings each card back right before you'd forget it.
Free to start. No credit card required.
Most math exams test whether you can apply a method under time pressure, and you can't apply what you can't recall. When the quadratic formula, the derivative rules or the unit circle come to mind instantly, your working memory is free for the actual problem. Spaced repetition keeps those foundations within reach for the whole course, not just the week you learned them, while practice problems build the skill of using them.
New accounts can add starter decks for math in one click, written with real notation. They're ordinary decks, so you can edit them, add your own cards, or import the ones you already have from a CSV file.
Shown the way Space Repeat shows them, formulas and all: one clear question, one short answer.

Make a card for each formula, rule and definition as your class reaches it, and write the formula itself on the back, not just its name. The Math & code toolbar inserts the notation if LaTeX is new to you.
Review your cards before you start a problem set: ten minutes of recall makes the problems faster. Keep doing the problems; the cards just make sure the tools are ready.
The algorithm tracks every card and shows it again right before you would forget it. No manual planning required.
Fractions, integrals, chemical equations and highlighted code look right on every card. Plain text works too.
Every feature, spaced repetition included, is free to use while Space Repeat is in beta. Early users will be looked after when pricing arrives.

Yes. New accounts can add starter decks for math: Pre-Algebra Essentials, Algebra 1: Equations, Lines and Factoring, Geometry Formulas, Algebra 2 and Trigonometry, Calculus: Derivatives, Calculus: Integrals, Statistics and Probability, Linear Algebra Basics. They're ordinary decks, so you can edit, add or delete cards, and write or import your own alongside them.
Yes. Put math between dollar signs and it's rendered with LaTeX, the notation math is written in: fractions, exponents, roots, integrals, sums, matrices and Greek letters. If you don't know LaTeX, the Math & code toolbar under each card field inserts the common pieces and shows a live preview.
Mostly no. Cards work best for things with one clear answer: a formula, a definition, the first step of a method. Keep practice problems for problem sets, and use cards so the facts those problems need are already in your head.
Yes, it's free while Space Repeat is in beta, with up to 50 decks and 100 cards per deck. Early users will be looked after when pricing arrives.
How to Study Math with Flashcards (Without Just Memorizing)
Flashcards won't teach you math, but they make the building blocks automatic: formulas, definitions, theorem conditions and first steps. Here's what to put on them, what to leave off, and how to mix them with problem practice.
How to Memorize Formulas (and When You Shouldn't)
Some formulas are worth knowing cold, some are better derived, and some can stay on the formula sheet. How to tell them apart, and how to make the ones you choose actually stick.
Space Repeat vs Anki
Anki is the most powerful spaced repetition tool ever built. It's also one of the most frustrating to set up. Space Repeat was built for learners who want the same scheduling logic with a fraction of the friction. Here's how the two compare across the things that actually matter.
Algebra Flashcard App
