About

Turing Machine Simulator

This application simulates Turing Machines, a fundamental concept in computer science and mathematics for analyzing algorithm computability. It offers a digital alternative to paper-and-pencil simulations, allowing users to write, execute, and analyze programs step-by-step with adjustable execution speeds.

Highlights
  • Turing Machine simulation
  • Program execution and analysis
  • Step-by-step execution
  • Adjustable execution speed
  • Export/import programs via email
  • Includes example programs

This app is a Turing Machine Simulator. Students of computer science and maths are probably familar with Turing Machines, because the Turing Machine is one of the important models when analyzing if mathematical problems or algorithms are computable. Usually dealing with Turing machines requires paper and pencil for simulating the program execution. This app can help by providing several ways to execute Turing programs and analyze it in an easy and comfortable way. You can write new programs for the Turing Machine, execute them and analyze the execution even step by step. It's also possible to change the speed of the execution. It's possible to export and import Turing programs using email. The app comes with some example Turing programs to play with.

Read full description

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.

Verdict

The call

The clearest difference is price: ARURAKU at Free against Turing Machine Simulator's $2.99. ARURAKU also leads on update cadence (every 2 months vs every 16 months). Turing Machine Simulator's advantage is ads (none vs shown) and iOS requirement (15.0 vs 17.0). On in-app purchases and device support there is nothing between them.
