About this app

Think in Structures. Understand Algorithms. Write Better Code. VisuStruct makes programming logic visible. Design algorithms visually using Nassi-Shneiderman diagrams, run them step by step with the built-in simulator, and turn your structures into real code — without getting lost in syntax. Whether you are learning programming, teaching computer science, or explaining algorithms, VisuStruct helps you focus on what really matters: understanding how a program works. Visualize. Simulate. Understand. Program. Why VisuStruct? • Build algorithms visually with an intuitive editor • Create Nassi-Shneiderman diagrams quickly and clearly • Execute algorithms step by step — like a visual debugger • See exactly how your algorithm flows • Generate code automatically • Learn programming logic before worrying about syntax • Perfect for students, teachers, and programming beginners From your first algorithm to more complex control structures, VisuStruct bridges the gap between **thinking about a solution and writing code**. Stop guessing what your program does. See it.

What's new

Version 1.6.1 · Oct 23, 2026

VisuStruct now feels right at home on iPhone! • Much more room for your structogram: the title takes just one line, and the inspector stays tucked away until you need it. • Elements at your fingertip: tap where you want to insert, and the element list opens right there. • Tap an element to edit its text right away. • No more surprise keyboard when you open a file. Also new: • Smarter simulation: conditions understand text comparisons, parentheses and "not" (!), integer division works like in Java, and Exit and Call blocks now run. After an error, the simulation stops right at the block that caused it. • Code export turns nested branches into "else if" (Python: "elif").
