SNU LEI Hangeul (Hangul: 한글; RR: Hangeul) is an application designed to assist non-Korean foreign language learners in learning to speak Korean. It is designed to make learning to speak Korean easier for the users by breaking the language down into its basic parts, called Hangul, and providing the user with a learning experience that is both easy to understand and fun to engage in. The application provides both phonetic and visual representations of the Hangul, as well as an interactive component that allows the user to check their own phonetic knowledge.

The application is available in three different languages: English, Japanese, and Chinese.

SNU LEI Hangeul can be used in a number of ways. The user can simply use the application as it is, with no additional configuration, as it is designed to be easy to use and understand. The user can choose to use the application in a more advanced way, by configuring the application to their needs, and the user can also opt to use the interactive component to check their knowledge of the phonetics of the language.
