K-Learn is a mobile app concept designed to help users learn Korean through structured, level-based lessons combined with cultural immersion and interactive practice.

The app is built around four core sections:

K-Course — Level-based lessons (Level 1–4+) covering grammar topics like word order, sentence negation, and "to be/have" verb forms, with a chat-style lesson format that includes explanations, voice practice (record & playback), and progress prompts leading naturally into testing.

K-Test — A structured quiz system organized by level and topic, with multiple-choice translation exercises, instant feedback (correct/incorrect highlighting), and a results summary screen showing overall score.

K-Culture — A content hub (Food / Travel / Podcast tabs) surfacing bite-sized cultural articles and vlogs — market food guides, travel spots, and short-form language-in-context videos with vocabulary breakdowns.

Premium/Monetization — A subscription paywall (Premium Pro) gating access to further levels once free content is exhausted.

You can form the content of the test. Choose the levels and lessons that should be in the test. The test result is saved and incorrect answers can be viewed

The lesson is presented in the form of a chat with the teacher in the messenger. The user has to type answers or record voice messages

Articles about Korean culture and podcasts, vlogs where people film real conversations are posted. This helps keep you motivated to learn. The podcast helps to develop listening skills.

The UI uses a soft lavender/orange accent palette on a clean white/light-gray base, with clear typography hierarchy and consistent navigation (bottom tab bar across all sections) to keep the experience simple and approachable for language learners at any level.

The design connects learning, testing, and cultural context into one cohesive flow — lesson completion naturally prompts a test, and cultural content reinforces vocabulary learned in-course, making the app feel like a complete learning ecosystem rather than isolated features.
