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, every answer and every worked step in Nabla is checked by a computer algebra system before it ever reaches you. No scraped question banks, no answers that sound right and are not. When Nabla shows you a solution, the math behind it has been checked. SEVEN COURSES • Calculus I — limits, continuity, derivatives, product, 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 • Math Foundations — order of operations, fractions, exponents, polynomials, factoring, inequalities, graphs, functions: the refresher before calculus 1,800+ computer-checked problems across 100+ skills. HOW IT WORKS Every skill teaches before it tests: build the idea from zero, see it in a worked example, then make it stick with practice. Worked solutions show the plan, each move, and why the move is allowed. Reveal them one step at a time. 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. If a lesson builds on something you haven't shown yet, a quick warm-up checks it first, and the refresher is one tap away. A skill counts as mastered only after a clean run on questions you haven't seen. Missed questions come back later. BUILD THE HABIT Daily goals, XP, levels, streaks with a streak freeze, and one reminder at the time you choose. Del, your math spotter, coaches you and celebrates every rep. WIDGETS Del's Formula Deck puts a formula from your course on your Home Screen or Lock Screen, a new one every hour, and you flip it like a flashcard. Del's Next Move shows your next lesson and today's goal. FORMULA SHEET Every formula in your course, searchable: what it says, when to reach for it, where it goes wrong, and a one-line worked example. EXAM MODE (PRO) Timed, mixed questions, no hints — the same pressure as the real exam. Then every miss worked through. WORKS OFFLINE The full problem bank ships inside the app. No account, no sign-up, no internet required to practice. Your progress stays on your device. FREE AND PRO The first unit of every university course is free, and Math Foundations is free in full. Nabla Pro unlocks every remaining unit, unlimited hearts, Del's full hint ladder, and Exam Mode.
