Mathji Math Practice & Quizzes

Mathji is a math practice app for kids in grades 1-12 that nails the whole loop: generate, correct, and track.

• Smart question generation: 200+ topic types from elementary through high school (including AP Calculus and electives), generated on the fly so they never repeat. • Adaptive difficulty: automatically adjusts to your child's performance — steps up when it's too easy, eases off when they get stuck. • Mistake notebook + personalized review: wrong answers are saved automatically and disappear once corrected; future practice prioritizes the topics your child hasn't mastered yet. • Parent dashboard: PIN-protected. See an all-grade learning spectrum, topic mastery, recent sessions, and exactly which questions were missed and what the child picked. • Rewards: kids earn points they can redeem for rewards you define, keeping motivation high. • Five languages: Traditional Chinese, English, Japanese, Korean, and Spanish — for both questions and explanations.

Privacy first: all data lives only on your child's device and in your private iCloud (CloudKit); the developer cannot access it. No ads, no in-app purchases, no external links.
