DaemonCore: Learn Kotlin v1 is a guided desktop workbench for beginners. Follow 48 lessons across 16 modules, starting with setup, variables, functions, and classes, then moving into collections, files, testing, coroutines, and application development. Write and run Kotlin in the built-in code lab. Work through examples and checkpoints, save drafts and notes, and use six project plans to turn what you learn into practical work. Your progress is saved locally, so you can pick up where you left off. The app includes the Kotlin compiler and Java runtime. You can start learning without setting up a separate development environment.
