About

i

This app is an interpreted programming language designed for educational purposes, focusing on functional programming capabilities. It allows users to test calculations, recursion, and array usage, serving as a teaching tool rather than for developing full applications.

Highlights
  • Functional programming
  • Global and local variables
  • Polish notation calculations
  • Recursive testing
  • Array usage
  • Interpreted language

LOGO was created in 1967 for educational use, is a computer programming language with functional programming capability. This version of LOGO is an interpreted language, but isn't a lite version. Functional programming with global and local variables is implemented. You can test calculations with polish notation, test recursively, and use arrays. LOGO is not a language for programming a real application, instead it is a teaching language.

Simple commands, deep thinking. Turtles is a turtle graphics programming app for elementary school students and beginners. Draw shapes while learning the basics of programming, including loops, variables, and functions. Give commands to the turtle on the screen to draw lines, create shapes and patterns, and build interactive projects. Before memorizing difficult syntax, learners can build a program, run it, see the result, and improve it step by step. Turtles can be used for children’s first programming experience, adult learning, school lessons, coding classes, and workshops. It also works on iPhone, but a larger screen such as iPad is recommended for creating projects. Sample projects and related information are available on our website. https://turtle360.net/ First Steps in Programming: Turtles is a programming app that helps learners think by combining simple commands. Starting with basic commands such as “move forward,” “turn right,” and “repeat,” even first-time programmers can quickly begin experimenting and learning by doing. Learn Programming Basics: By drawing shapes, learners can understand important programming concepts such as sequencing, loops, conditions, variables, and functions. Because the result appears immediately on the screen, it is easy to understand how a program works. Try More Advanced Expressions: After learning the basics, learners can try more complex shapes, patterns, and fractal drawings. They can also explore ideas connected to computer science, such as recursion, in a natural and visual way. Create Mini Games and Projects: Turtles is not only for moving a turtle. Learners can also create interactive projects and simple mini games based on their own ideas. By combining the commands they have learned, they can experience the joy of thinking and creating by themselves. About Turtle Graphics: Turtle graphics is a programming method where learners give commands to a turtle on the screen to draw shapes. It was developed in the 1960s for the LOGO programming language, and it is still used today in many programming learning environments. Turtles is designed based on this idea so that both children and adults can enjoy learning programming. Acknowledgments: Turtles was inspired by many programming languages and learning environments, including LOGO, Squeak Etoys, Scratch, Python, and Swift. We thank the developers around the world who created and nurtured these ideas.

Turtles is free to download; i costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

i holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 3 and 13 respectively. Written reviews complicate that: 80% of i's written reviews are positive against 90% of Turtles's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

i ships an update every 7 months, Turtles monthly. The most recent releases landed on September 25, 2026 and October 4, 2026 respectively.
