CodeMaster — Learn Programming Through Practice

CodeMaster helps you learn programming languages step by step with interactive exercises. No boring lectures — just hands-on practice with instant feedback.

9 Programming Languages: • Kotlin • Python • JavaScript • Java • Swift • C++ • Go • TypeScript • C#

5 Question Modes: • Knowledge Check — multiple-choice quizzes on language concepts • Output Predictor — read a code snippet and guess what it prints • Bug Hunter — spot the error in broken code • Flashcards — memorize key terms and definitions • Algorithm Challenge — solve logic and algorithm problems

Structured Learning Paths Each language has topics organized from basics (variables, types, control flow) to advanced concepts (OOP, lambdas, coroutines). Lessons unlock progressively as you complete them.

Track Your Progress • Day streak counter to keep you motivated • Per-language completion stats and accuracy percentage • Daily Review mode resurfaces questions you got wrong

Privacy-First & Offline All progress is stored locally on your device. No account required, no internet needed, no ads, no analytics. Just you and the code.

Start with the language you're curious about and work through the path at your own pace.
