AlgoBubbles vs Codey

Algorithms become easier when you can see every step. AlgoBubbles turns 33 computer-science algorithms into clear, interactive animations. Move forward or backward one step at a time, play the full sequence, and understand what each comparison, swap, or graph visit means. LEARN WITH CONTEXT • Compare best, average, and worst-case time complexity • See space complexity and practical use cases • Read clear explanations for every animation step • View implementation code in Swift, Python, and JavaScript BUILD REAL PROGRESS • Search the full algorithm catalog • Track completion by category and across the app • Learn through Arabic or English with full RTL support • Start with a short, value-first onboarding guide • Continue learning offline without creating an account EXPLORE 33 ALGORITHMS Sorting, searching, graph traversal and shortest paths, data structures, string matching, dynamic programming, cryptography, and divide-and-conquer techniques. Four algorithms are free. A single optional premium purchase unlocks the remaining 29 algorithms and removes ads—no subscription. Download AlgoBubbles and turn abstract algorithms into visible, understandable steps.

Learn to code the fun way — no experience needed. Codey turns learning to program into a game. Instead of staring at a blank screen, you drag colorful code blocks into place to write real Swift — the same language used to build iPhone and Mac apps. Solve bite-sized puzzles, earn XP, build a daily streak, and watch your skills grow one lesson at a time. WHY CODEY • Real code, not toy syntax — you write actual Swift from day one • Game-style lessons — drag blocks, solve puzzles, earn XP and badges • Truly for beginners — every idea explained in plain language • Learn by doing — a free Playground to experiment anytime • Your two modules are completely free • No-ads.!!! ALWAYS WHAT YOU'LL LEARN 15 modules • 90 lessons • hundreds of hands-on challenges — from your very first line of code to building real apps: • Fundamentals: types, printing, variables, conditionals • Loops & collections, functions & closures • Optionals, object-oriented programming, and advanced topics • Building apps: SwiftUI, networking, saving data, app architecture, testing, accessibility & animations ALSO INSIDE • Daily challenges to keep your streak alive • Mastery quizzes to lock in each module • Shareable certificates when you finish a module • A home-screen widget for your streak • Available in English and Greek Start free today and write your first line of code in minutes.
