Mathio vs C++

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. After that, the Continue card always suggests your next lesson. ▸ DAILY GOAL + STREAKS Set a daily goal and build a streak. 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. Extra keys like a comma or comparison signs appear when a question needs them. ▸ EXAM SPRINT (PREMIUM) 10 mixed questions from your review queue, your weak spots, and your next lesson. Great for quick exam prep. ▸ FORMULAS + SEARCH Bookmark formulas as you learn them, and search across topics, lessons, and formulas. ▸ STATS Follow your progress with statistics and an activity calendar. ▸ DAILY REMINDER An optional reminder that skips the days you've already practiced. ▸ SIRI + SHORTCUTS Say "Practice math with Mathio" to jump straight into practice. ▸ BUILT FOR EVERYONE Dark mode, VoiceOver, larger text sizes, iPhone and iPad. Available in 25 languages. ▸ PRIVACY-CONSCIOUS Learning progress stays on your device. No ads, no leaderboards. Mathio does not sell personal data. RevenueCat is used only to validate subscriptions.
