This Korean keyboard features large keys, diphthongs using dotted dots (ㆍ + ㅏ = ㅑ, ㆍ + ㅜ = ㅠ, etc.), and tense sounds obtained by rapid tapping. Its unique features include a thorough probability-based next word suggestion function, a two-line arrangement of relatively low-frequency letters (scroll-based numbers, symbols, and Roman letters), and a prioritization of high-frequency letters in Roman alphabetical order, enabling fast, error-free typing with minimal effort.

It also provides Chinese character input.
It features a shortcut key binding feature for common phrases.
The key display occupies less than one-third of the screen, maximizing space for primary apps.

This keyboard is a favorite for both Korean and English users.

The free trial is available, with a one-time in-app purchase for lifetime use.
