iPhone
Master math with science-backed spaced repetition. Practice calculus, algebra & linear algebra with ease. No ads, no distractions - just focused learning.
Math Zen is a focused math practice app that uses spaced repetition to help you truly master calculus, algebra, and linear algebra.
Unlike math solvers that give you answers, Math Zen generates unlimited practice problems and uses the SM-2 spaced repetition algorithm to schedule reviews at the optimal time - so you actually remember what you learn.
SPACED REPETITION
Math Zen tracks your performance across every topic and automatically schedules reviews before you forget. Based on the proven SM-2 algorithm used by medical students and language learners worldwide.
HANDWRITING RECOGNITION
Write your answers naturally with your finger or Apple Pencil. On-device handwriting recognition means your work stays private and works without internet.
6 TOPICS, 35 PROBLEM TEMPLATES
- Algebra: simplify expressions, factor polynomials, solve equations
- Derivatives: power rule, chain rule, product rule, trig derivatives
- Limits: direct substitution, factoring, L'Hopital, infinity
- Integrals: power rule, definite integrals, u-substitution, trig
- Vectors: addition, dot product, magnitude, scalar multiplication
- Matrices: determinants, trace, eigenvalues, multiplication
ADAPTIVE DIFFICULTY
Problems adjust to your mastery level. As you improve, difficulty increases. Struggling? The app backs off and reinforces fundamentals.
MASTERY TRACKING
Track your progress with mastery scores (0-100) for each topic, XP progression, streaks, and detailed accuracy stats.
WEEKLY LEADERBOARD
Compete with other learners on the weekly ranking. See how your correct answers stack up. Sign in to join the leaderboard and track your rank.
DAILY REMINDERS
Set a daily practice reminder so you never break your streak. Customize the time that works for you - all notifications are local and private.
DESIGNED FOR FOCUS
A clean, minimal interface with no ads, no social features, no gamification gimmicks. Just you and the math.
WORKS OFFLINE
All problems are generated on-device. Practice on the subway, on a plane, or anywhere without internet. Your progress syncs to the cloud when you're back online.
