The purpose of the TOPIK Locker is to help users learn the Korean alphabet. To achieve this, we've designed the application in two different ways: flashcard and quiz.

The first option, flashcard, allows you to use your mobile device to both learn and memorize Korean characters. This option will be available to you from the very first level, which contains only the most basic Korean characters.

The second option, quiz, allows you to recognize the characters based on their appearance. This option is only available from the second level onwards.

Each time you pass a level, the application will increase the difficulty of the characters you are learning, allowing you to better understand and remember them.

The application is designed to allow users to learn at their own pace. To this end, we've made it possible to repeat the words as many times as necessary and to assess your progress.

The application allows users to learn a word at a time. After you have learned the word, it is no longer presented to you. Instead, you are given the opportunity to recognize the word, which is done through a series of questions.
