Mathio vs Nabla

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.

Math you can actually trust. Nabla is deliberate practice for university math — the courses engineering and STEM students have to pass. Learn the idea, see a worked example, then drill it until it sticks. VERIFIED, NOT GUESSED Every problem and every answer in Nabla is generated and independently checked by a computer algebra system before it ever reaches you. No scraped question banks, no AI-written answers that sound right and are not. When Nabla shows you a solution, the math behind it has been proven. SEVEN COURSES • Math Foundations — order of operations, fractions, exponents, polynomials, factoring, inequalities, graphs, functions • Calculus I — limits, continuity, derivatives, product and quotient and chain rules, related rates, optimization, integrals, the Fundamental Theorem • Calculus II — integration by parts, partial fractions, improper integrals, sequences and series, Taylor series, parametric and polar curves • Linear Algebra — vectors, matrix products, row reduction, determinants, inverses, linear independence, rank, projections, eigenvalues • Multivariable Calculus — vectors in 3D, partial derivatives, gradients, directional derivatives, tangent planes, double and triple integrals • Differential Equations — separable, linear and exact equations, stability, characteristic roots, oscillations, Laplace transforms, ODE systems • Probability & Statistics — counting, conditional probability, Bayes' rule, distributions, confidence intervals, hypothesis tests, regression 1,500+ verified problems across 91 skills. HOW IT WORKS Each skill opens with a concept lesson and a worked example, then a focused set of practice problems. Get one wrong and you see exactly where the reasoning broke — Nabla names the specific misconception behind the answer you picked, not just a red X. Del, your math spotter, hands you a strategy hint before the full steps. Streaks, XP, levels, daily goals, and weekly leagues keep you coming back. Spaced review brings problems back before you forget them. EXAM MODE Timed, mixed, no hints, no feedback until you hand it in — the same pressure as the real paper. Then a topic-by-topic breakdown showing exactly where the marks went, with the weakest skill first and a route straight into it. WORKS OFFLINE The full problem bank ships inside the app. No account, no sign-up, no internet required to practise. Your progress stays on your device. FREE AND PRO The opening unit of every course is free — a real place to start in all seven, not a demo. Nabla Pro unlocks every remaining unit, removes the hearts limit, opens Del's full hint ladder, and enables Exam Mode. No ads. No account. No data sold. ——— Nabla Pro — auto-renewing subscription • Monthly • Yearly (best value) Prices are shown in your local currency inside the app before you purchase.
