ARURAKU - Algorithms in Motion

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.
