Byeolbyeol Hangul is a Korean vocabulary learning app for young children.
It combines word cards, audio guidance, and playful learning games to help children learn Hangul naturally.

1. Word Card Learning

Children can begin learning by selecting a variety of word cards from the main screen. Each card features visual images and vocabulary designed to help children recognize the word.

2. Voice Guidance Learning

When a word card is selected, the corresponding word's pronunciation is played aloud, helping children learn both letters and sounds. Repeated playback facilitates natural pronunciation learning.

3. Playful Minigames

This app includes a minigame where children drag and drop Korean consonants and vowels to complete syllables.
Through this process, children can experience the structure of consonants and vowels, final consonants, and double vowels in a playful way, helping them understand the principles of Hangul.

4. Learning Progress and Rewards

Stars and progress indicators are provided based on learning progress, encouraging children to feel a sense of accomplishment and continue learning.
