Hybrid Keyboard is an Android app developed by TJTM Soft that aims to improve the Korean typing experience. It combines the single vowel keyboard with a sliding method to make it easier to input consonants. The keyboard allows users to input numbers and symbols with a sliding motion as well. Additionally, it offers features such as Chinese and Japanese character input and emoji.

Users can customize the keyboard by adjusting the spacing between keys to fit their preferences. They can also opt for the two-set keyboard or the single vowel keyboard with six rows, which provides a more balanced arrangement for consonants and vowels. Furthermore, the one-handed keyboard is available for situations when only one hand is free.

Hybrid Keyboard has a warning message when registering the app, but it does not access personal information. It only requires permissions for vibration and external storage backup. If users encounter any issues while using the app, they can contact the developer with specific details, and the developer will try to fix them as soon as possible.
