## What is TddStudy?

TddStudy is a quiz and interactive reading app that helps developers build knowledge through short daily study and adaptive review. See what to study next on Home, then move naturally from results into wrong-answer review or the next lesson.

Build a small habit with a five-question daily goal and study streak. Review questions selected from your learning history, retry missed concepts from Wrong Answers, and explore Android, iOS, and backend courses organized by level.

Interactive books connect chapter reading with checkpoints and tests. Each submitted answer includes immediate feedback and an explanation, while results prioritize review, wrong answers, and the next learning action.

Korean and English content, light and dark themes, and offline study for downloaded quiz packs and installed books are supported.
