## What is ARURAKU?

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.
