Learn Raku brings the full Course of Raku by Andrew Shitov to your phone for offline reading. It contains 375 lessons across seven parts — from the essentials through objects, regexes and grammars, and functional, concurrent, and reactive programming — along with 209 interactive quizzes, 395 exercises with worked solutions, and full-course search. The app works fully offline and collects no personal data.
Tap the theme button in the top-right of the home screen. Each tap cycles through System, Light, and Dark. “System” follows your device setting; Light and Dark override it. Your choice is remembered the next time you open the app.
Progress is stored only on your device. A lesson is marked complete when you tap “Next” or the check mark on the lesson screen, and the app remembers the last lesson you opened so you can resume from the home screen. Nothing is uploaded anywhere.
Each quiz is a multiple-choice question. Select your answer (or answers) and check it — the app shows which options were right or wrong and explains why, so a quiz doubles as a quick way to learn.
No. All lessons, quizzes, exercises, and solutions are bundled with the app and work completely offline. A connection is only used if you tap an external link, such as the official Raku documentation.
You can tap the check mark on any completed lesson to mark it as not done. To clear everything at once, reinstalling the app removes the locally stored progress.
Thank you — please email us the lesson title and what should change. Corrections are always welcome and help improve the course for everyone.
