ARURAKU - Algorithms in Motion

Learn algorithms by watching

Free · Designed for iPad. Not verified for macOS.

Algorithms set in motion. Watch bubble, quick, merge, and heap sorts come alive — learn by seeing, not by reading. An educational visualization app that lets you UNDERSTAND algorithms by watching them — not by reading. Three classic areas of computer science come alive with interactive animations: Sorting, Searching, and Recursion. [ Sorting - 6 algorithms ] - Bubble Sort / Selection Sort / Insertion Sort - Merge Sort / Quick Sort / Heap Sort Race Mode runs multiple algorithms side by side on the same array — feel the difference in complexity at a glance. [ Searching - 4 algorithms ] - Breadth-First Search (BFS) / Depth-First Search (DFS) - Dijkstra's Algorithm / A* Search Visualize pathfinding on a grid maze. You can place walls yourself. [ Recursion ] - Tower of Hanoi - Fractals: Koch curve, Sierpinski triangle, recursive tree [ Features ] - Grasp WHAT IS HAPPENING through color and motion - Adjustable speed, step-by-step execution, multiple array presets - Each algorithm includes mechanism, complexity, pros and cons, and real-world usage notes - Ads never interrupt the animation - designed to preserve focus - Universal app for iPhone and iPad - Japanese and English (follows OS language) [ Who is this for ] - Students learning programming for the first time - Anyone preparing for IT exams - Engineers who want to deepen their intuition about algorithms - Curious minds who love watching things move [ Note on pricing ] This app is completely free with no in-app purchases or subscriptions. To support development and maintenance we display Google AdMob banner and interstitial advertising. Ads are never shown while an algorithm animation is playing. The first information-systems title of the Raku Series.
