This educational and visualization app helps you understand algorithms not by "reading" them, but by "seeing them in action."

Experience three areas—sorting, searching, and recursion—through interactive animations.

【Included Algorithms】
■ Sorting (6 types)
・Bubble Sort / Selection Sort / Insertion Sort
・Merge Sort / Quick Sort / Heap Sort
The "Race Mode" allows you to run multiple algorithms simultaneously on the same array, giving you a clear visual representation of the differences in computational complexity.

■ Searching (4 types)
・Breadth-First Search (BFS) / Depth-First Search (DFS)
・Dijkstra's Algorithm / A* (A*-Ster)
Visualize pathfinding behavior in a grid maze. You can tap and edit walls yourself.

■ Recursion
• Tower of Hanoi (3-8 images)
• Fractals such as Koch curves, Sierpinski triangles, and recursive trees

【Features】
• Intuitively understand "what's happening now" through color and movement
• Supports speed adjustment, step-by-step execution, and array pattern switching
• Each algorithm includes explanations of its mechanism, computational complexity, advantages/disadvantages, and real-world applications
• No ads during animation playback, designed to maintain immersion
• Smartphone/tablet compatible
• Supports both Japanese and English (follows device language settings)

【Recommended for】
• Students and beginners learning programming
• Those preparing for exams such as the Fundamental Information Technology Engineer exam
• Engineers who want to intuitively understand how algorithms work
• Intellectually curious individuals who "like watching things move"

【About Usage】
This app is completely free. There are no in-app purchases or subscriptions. To maintain and improve the app, we display ads (banner and full-screen ads) via Google AdMob, but the app is designed to not display any ads during animation playback.


The first in the "Easy Series" information-based category.
