Mathio vs Euclid Lab

Math, made simple. Practice that remembers your mistakes. Mathio is a calm, focused math trainer for school, homework, exam prep, university refreshers, and self-study. Short lessons, a spaced-repetition review queue, a mistake book, and a formula reference work together in one clean learning flow. WHO MATHIO IS FOR • Students who want structured practice for homework, quizzes, and finals • Learners preparing for exams who prefer short, mixed sessions to random worksheets • Parents looking for a clear math app without ads or leaderboards • Self-learners rebuilding fundamentals in algebra, calculus, statistics, finance, or discrete math • Anyone who learns better with a few focused minutes every day than with one stressful cram session ▸ EASY START A short onboarding with a quick level check.

Streak freezes cover the days you miss. ▸ SPACED REPETITION Questions come back in your Review queue after 1 day, 3 days, 1 week, 2 weeks, and 1 month. ▸ MISTAKE BOOK Every missed question is saved and returns in a focused drill until you answer it correctly on two separate days. ▸ HINTS + STEP-BY-STEP SOLUTIONS Stuck? Open a hint. Wrong answer? You see the full worked solution right in the exercise. ▸ MATH KEYPAD Enter answers on a keypad made for math: numbers, fractions, powers, roots, and π.

Explore the 48 propositions of Book I of Euclid’s Elements through reading, construction and proof practice. Euclid Lab separates proposition reading, straightedge-and-compass work and reasoning so you can focus on one activity at a time. Arrange supplied proof blocks to connect premises to conclusions. Scored exercises use semantic checks of geometric relationships and logical dependencies, not the appearance of a drawing or AI grading. Progressive hints and complete solutions, shown on request, help when you get stuck. I.7 currently offers unscored reading, exploration and notes. Freehand notes are also unscored and are not automatically verified as correct proofs. Foundations and I.1–I.12 are free. I.13–I.24 and I.25–I.48 are separate, one-time in-app purchases. Buying one pack does not unlock the other. No subscription is required. Learning progress and notes are stored locally on your device. Learner profiles are not Apple Accounts, and no Euclid Lab account registration is required. Restore Purchases restores eligible content access; it does not synchronize learning progress.
