Logo brings the classic turtle graphics programming language to iPhone and iPad. Write a few commands, watch a turtle paint the screen, and discover the joy of programming.
Logo is designed for students, educators, and curious beginners. Simple commands, instant feedback, beautiful results.
Move a turtle around the screen with FORWARD, RIGHT, LEFT, and BACK. See your code come alive.
Code is colorized in real time, so commands, numbers, and comments are easy to read.
Spirals, flowers, polygons, fractals — load a program and tweak it to make it your own.
Adjustable animation speed. Watch each step, or run the whole program in a flash.
Experiment fearlessly. Step backwards and forwards through your changes with confidence.
Your saved programs follow you across iPhone and iPad automatically and privately.
Pick pen colors, line widths, and background colors. Make geometric art that pops.
A friendly reference for every command — perfect for classrooms and self-learners.
The REPEAT command turns simple ideas into intricate patterns. Math becomes visible.
Logo is built for learners. No third-party SDKs, no subscriptions, no nags.
The same primitives that powered classroom Logo since 1967, polished for touch.

Logo's full functionality is available to everyone — no subscription, no unlock screens. If it helped you learn or teach, you can leave a tip directly in the app.
Logo is designed to be safe for students of every age. No accounts, no analytics, no tracking.
Open the app and start coding. No sign-in, no email required.
No analytics SDKs. No ad networks. No usage telemetry.
Sync stays inside your private iCloud account. We can't see your code.
No collected data, ever. Designed to be appropriate for learners of all ages.
Students learning to code, educators teaching programming, parents introducing kids to coding, and anyone curious about how computers turn instructions into pictures.
None at all. Logo's commands are plain English — FORWARD 100, RIGHT 90, REPEAT 4 — and you'll be drawing shapes within minutes.
Yes. Logo is universal and runs natively on both, with iCloud sync to keep your saved programs in step across devices.
Only optional tips. They never unlock features. Logo's full functionality is available to everyone with no purchase required.
Movement (FORWARD, BACK, RIGHT, LEFT, HOME), pen control (PENUP, PENDOWN, SETPENCOLOR, SETPENWIDTH), and loops (REPEAT), plus comments for documentation.
Questions, feedback, classroom ideas, or a command you'd love to see? I'd love to hear from you.
