Free, for iPhone, iPad, and Android.
Learn Raku brings the complete Course of Raku by Andrew Shitov to iPhone, iPad, and Android — a full, structured course on the Raku programming language that works entirely offline. And the examples run, right on your device.
Whether you are new to programming or coming from Perl, Python, or another language, Learn Raku takes you from the essentials all the way to advanced topics, with real code examples, interactive quizzes, and hands-on exercises every step of the way.
Run the code, not just read it
The app carries Raku++, our complete implementation of the Raku language, compiled for the device itself. Tap Run under an example and see what it prints, right under the code — and when a program asks for input, type your answer. Open the example in the Playground, change it, and run it again: no internet connection, no server, no setup.
What you will find inside:
- 399 lessons across six parts — from the basics of variables, types, and control flow, through objects, I/O and exceptions, regexes and grammars, and functional, concurrent, reactive, and web programming
- Over a thousand runnable examples — tap Run to see the output, or open any example in the Playground to experiment
- The Playground — write your own Raku programs, with syntax highlighting, a symbol bar for the characters Raku needs, program input, and 22 example programs to explore
- 216 interactive quizzes — answer multiple-choice questions and get instant feedback, with an explanation for every option
- 396 exercises with worked solutions — solve each one in the Playground, then reveal the solution to compare
- The Final Test — a hundred questions across the whole course, each checked the moment you answer, with a full review at the end
- Full-course search — jump to any lesson, quiz, or exercise instantly
- Progress tracking — lessons are marked as you go, and a “Continue” card takes you back to where you left off
- Light and dark themes — System, Light, or Dark
Fully offline, private by design
Everything is bundled with the app. There is no account to create, no ads, and no tracking: the app collects no personal data, and your progress and your programs stay on your device.
The course and the compiler
Learn Raku is the mobile edition of our free Raku Course, which is also on the web at course.raku.org. The code in the app runs on Raku++, the Raku compiler we build — free to download for macOS, Linux, and Windows, and running in the browser too.
Raku (formerly Perl 6) is an expressive, multi-paradigm language with first-class support for object-oriented, functional, and concurrent programming, plus one of the most powerful grammar and regular-expression engines of any language. Learn Raku is a great way to learn it at your own pace, wherever you are.
