A flash card and quiz app to test your Korean vocabulary for the TOPIK exam.

Both a flash card and a quiz tool, TOPIK Locker is designed to help enthusiasts and beginners alike, learn and recognize the basic Korean characters through clever repetition and memorization of the 6,000 most commonly and frequently used Korean characters.

The six thousand words are based on the official Korean word list as released by the National Institute of Korean Language (국립국어원), the South Korean government language regulatory body and is widely used as the foundation in preparation for the TOPIK exam (Test Of Proficiency In Korean).

For this app, the 6,000 characters are separated to 6 distinct levels in order of increasing complexity. The app starts with only characters from level 1 whether for flashcard or quiz. As the user gain familiarity of the existing characters, the app will adjust the word list to gradually include characters from subsequent levels, i.e. one by one, from level 2 to level 6. The learning/relearning of new words are relayed via informative flashcards or directly tested depending on the user's preference.

Character recognition is reinforced through repeated exposure and testing. The user's familiarity with the individual characters are assessed by the 'depth' of the character that defaults at 4. For every correct answer in the quiz, the depth of the character decreases whereas for every incorrect answer, the depth increases. Over time, for any character that the user manage to get to depth value of '0' and will be stored away in the 'Locker', thus giving way to new characters to arise, aiding digestion.

TOPIK Locker is suitable for both beginners and advance enthusiast alike, acting like a personal trainer that remembers your familiarity and understanding of each and every word, word by word, step by step, help you make your way through the nearly 6,000 characters at your own pace.
