# Nabla: College Math — Pass Calculus, Diff Eq & more > Pass Calculus, Diff Eq & more (iPhone/iPad app by Muhammed Hamza Cakmak.) - Source: https://appshunter.io/ios/app/nabla-college-math/id6796978565 (this page in markdown: same URL + `.md`) - Developer: [Muhammed Hamza Cakmak](https://appshunter.io/developer/1884048817) - Category: Education, Productivity - Price: Free with in-app purchases - Age rating: 4+ - Requires: iOS 16.4 · 87 MB - Languages: American English - Released: 2026-08-18 - Data updated: 2026-10-05 - User reviews in markdown: https://appshunter.io/ios/app/nabla-college-math/id6796978565/reviews.md ## What is Nabla? 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.

Flip it like a flashcard (When to reach for it → Show formula → Knew it / Next) without opening the app. On the Home Screen and the Lock Screen. • Del's Next Move widget: your next lesson, streak and today's goal at a glance. • All 7 courses rebuilt to teach before they test: explore the idea, see it worked, then make it stick. • Worked solutions for every problem: the plan, each move, and why it's allowed. Every answer and step is checked by a computer algebra system. SMARTER LEARNING • Lessons now check what they build on. Missing a basic? You get a short refresher first, then you're right back where you left off. • Math Foundations is now completely free, so a refresher is never behind a paywall. • Mastery means something: a skill counts as mastered only after a clean run on questions you haven't seen, and the ones you miss come back later. • Wrong answers get a real diagnosis, and the options after a miss are clearer: try a similar one, replay that part of the lesson, or move on. POLISH • A shorter, smoother onboarding with no quiz before your first lesson. • A new first-look tour that shows you exactly what each part of Home does. • A redesigned Home that puts today's move first, even at large text sizes. • Smoother animations and lower battery use. • Many fixes across light and dark mode. ### 1.0.12 — 2026-09-21 • A short first-run tour: where to start, how hearts and streaks work, how to switch course, and where to find the formula reference. • The course picker now opens on your own course. • Smoother pop-ups, hint sheet and formula panel. • Fixed clipped button text and a few blank-screen bugs. • Faster launch and faster screen transitions. ### 1.0.11 — 2026-09-15 Getting started is faster and clearer. • New setup: pick your course, your deadline, your level and what trips you up. Four taps, then a plan built from your answers. • Your plan shows the whole course up front — how many topics there are, and exactly how much of it is free. • The first lesson is optional and takes two minutes. Mistakes cost no hearts, so you can just try it and see how a lesson feels. • Calculus I & II, Linear Algebra, Multivariable, Differential Equations and Probability & Statistics come first. Math Foundations is still there if you want the algebra refresher. • Del now remembers the mistakes you make and brings them back before they fade, with guided steps instead of just the answer. • Add the Home Screen widget and set a study reminder during setup, or skip both. • Tidier home screen and Exam Mode layouts, widget fixes on iOS 16, and Del finally waves properly. ### 1.0.10 — 2026-09-06 Meet the new Nabla Home Screen widget—see your next lesson, upcoming reviews, and daily goal at a glance. This update also brings a smoother onboarding experience, visual improvements, and performance fixes. ### 1.0.9 — 2026-08-31 A smoother, more interactive onboarding experience with Del. Improved home widgets and smart reminders. Review missed steps directly from lesson results. Navigate back through completed questions more easily. Improved readability for formulas and answer choices. Redesigned heart-limit and Nabla Pro prompts. Smoother app startup and screen transitions. General UI, spacing, stability, and performance improvements. ## Apps similar to Nabla | App | Rating | Price | Category | | --- | --- | --- | --- | | [Mathio: Math Practice](https://appshunter.io/ios/app/mathio-math-practice/id6767033115) | — | Free | Education | | [College4Less:Science](https://appshunter.io/ios/app/college4lessscience/id6748413913) | — | Free | Education | | [Aporia: Math & Physics](https://appshunter.io/ios/app/aporia-math-and-physics/id6792977784) | — | Free | Education | | [Faraday: STEM & Exam Prep](https://appshunter.io/ios/app/faraday-stem-and-exam-prep/id6781682888) | — | Free | Education | | [Thuztra Learn: Quant Finance](https://appshunter.io/ios/app/thuztra-learn-quant-finance/id6809566117) | — | Free | Education | | [MakesSense: Math Solver](https://appshunter.io/ios/app/makessense-math-solver/id6760540458) | 5.0 (10) | Free | Education | ## More apps by Muhammed Hamza Cakmak - [Takeover: Daily Habit Tracker](https://appshunter.io/ios/app/takeover-daily-habit-tracker/id6760352061) - [KPSS 2026: Soru Bankası Çöz](https://appshunter.io/ios/app/kpss-2026-soru-bankas-coz/id6786241499) - [Wood Block Puzzle - Brick Jam](https://appshunter.io/ios/app/wood-block-puzzle-brick-jam/id6798415934) - [DMV Permit Practice Test :2026](https://appshunter.io/ios/app/dmv-permit-practice-test-2026/id6798435772) - [CDL Prep: Air Brakes & Class A](https://appshunter.io/ios/app/cdl-prep-air-brakes-and-class-a/id6800135409) All apps by Muhammed Hamza Cakmak: https://appshunter.io/developer/1884048817 ## Related topics [nabla](https://appshunter.io/ios/topics/nabla) · [nabala](https://appshunter.io/ios/topics/nabala) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
