Built around learning, practice and retention.

01 · CURRICULUM

Structured from fundamentals to advanced topics

Beginner, intermediate and advanced progression with 94 C# topics and 187 structured subtopics.

02 · PRACTICE

Practical coding instead of passive reading

874 coding tasks, lesson knowledge checks and terminal-style exercises reinforce the course material.

03 · RETENTION

Progress, completion and streak mechanics

Persistent learner progress, completion states and streak-oriented UI are already part of the experience.

04 · LOCALIZATION

Four complete language versions

English, Polish, Ukrainian and Russian content with in-app language switching.

05 · MONETIZATION

Subscription architecture already implemented

Direct app-store billing with backend verification and server-authoritative entitlement handling.
