Graphing Calculator AR vs CodeArise

Graphing Calculator lets you visualize algebra and calculus interactively and experience 3D graphs in augmented reality on devices which support AR. Graph functions, implicit relations, parametric curves and surfaces, inequalities, points, vectors, contour and density plots, color maps, vector fields, ordinary differential equations, surfaces of revolution, coordinate transformations, conformal maps and complex-valued curves, surfaces, and ODEs. Use rectangular, polar, cylindrical, or spherical coordinates. Solve equations numerically, graphically, or symbolically. "Graphing Calculator is one of the best examples of elegant power and clean user interface of any application I've seen." - Bruce Horn, creator of the Macintosh Finder.

Learn Swift the way real iOS developers learn — one small focused step at a time. Learn Swift & Build Apps turns the language and the iOS ecosystem into a clean 26-topic path: from your very first variable to senior-level concepts. No 12-hour video courses, no overwhelm — just short daily sessions you actually finish. WHAT'S INSIDE • Lessons A structured Swift learning path that takes you through Variables, Optionals, Closures, Structs, Classes, Generics, Concurrency, and beyond. Each topic gives you the core idea, a real code example, common mistakes to avoid, and a quick mini-check. • Quizzes Find out what you actually know. Run the Swift Level Test (50 focused questions) to discover your real level — Beginner, Junior, or Middle — with topic-by-topic breakdown and XP rewards. Add specialized tests for SwiftUI, UIKit, iOS Fundamentals, and Advanced iOS. • Boss Battles Three themed quiz duels — The Optional Ghost, Memory Leak Hydra, and Concurrent Dragon. Each correct answer drains a chunk of the boss's HP; three wrong answers and the run is over. The mistakes you make stick. That's the point. WHY IT WORKS • A clear path — no more "what should I learn tomorrow?" • Bite-sized lessons — finish a topic on a coffee break • Practical examples — patterns you actually meet in real iOS work • A daily rhythm — XP, level, and streak keep you coming back • Native iOS feel — clean dark UI, smooth animations, no clutter FOR WHOM • New developers who want a concrete plan to learn Swift • Career switchers preparing for Junior or Middle iOS interviews • Indie developers building their first MVP • Working iOS engineers who want sharper foundations Your learning journey, in your pocket — ready every time you open the app. Privacy Policy: https://fleiron.github.io/learnswift/privacy-policy.html Terms of Use: https://fleiron.github.io/learnswift/terms-of-use.html
