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.
