The best apps to learn math as an adult, whether you are starting over or filling old gaps
Knowverse is first because its mathematics courses teach one idea at a time with visual flows and reveal cards, then bring the ideas back as flashcards and quizzes, next to 16 other subjects; Brilliant is the pick for guided problem solving in math and coding; Khan Academy for free school-style math from arithmetic to calculus with hints; Algebra Touch for hands-on algebra you move with your finger; Mental Math Cards for faster arithmetic in your head.
Many adults who left math behind at school want a math app for adults that lets them relearn math at their own pace without childish games. This adult math refresher skips kids' math games on purpose and focuses on step‑by‑step explanations, active recall, and short daily sessions so you can learn algebra as an adult and build confidence.
Knowverse is our own app. We rank it first for this need and explain why. Details about the other apps come from their App Store listings, checked on 2026-11-06.
Apps were ranked on three adult‑focused criteria. First, each lesson breaks a concept into one clear idea and explains it with adult‑level language and visuals. Second, the app forces practice and spaced recall through quizzes, flashcards or manipulatives so knowledge sticks. Third, the experience fits into a 5‑10 minute daily slot without requiring long sittings or childish gamification.
