## What is JittaKey?

JittaKey is an innovative keyboard app that supports Japanese input more efficiently and intuitively.
It adopts a unique Japanese keymap, allowing users familiar with Romaji input to use it smoothly without drastically changing their usual input method.

By using JittaKey, you can reduce the number of keystrokes by approximately 20%, significantly shortening the time required to compose messages or documents.

In addition, frequently used characters like the following can all be input with a single keystroke:

・Consonants in the “I” row (e.g., き [ki], し [shi], ち [chi])
・Small vowels (ぁ, ぃ, ぅ, ぇ, ぉ)
・Nasal sound “ん”, small “っ”, and long vowel “ー”
・Contracted sounds (ゃ, ゅ, ょ) and Y-row characters (や, ゆ, よ)
・Other characters like を, わ, ゎ, ヴ, punctuation mark "。", hyphen "―", etc.

With this, Japanese input becomes dramatically more efficient, offering a much more comfortable typing experience.

### 5/5 — 빠르고 편리합니다.

*2025-08-02*

키보드 배열과 빠르게 단어를 작성 할 수 있어서 좋습니다. 인터페이스도 깔끔하고 사용하기 쉽네요.

**Developer response:** 긍정적 평가에 감사 드립니다. 
현재는 '상용구 제안' 기능이 많이 약합니다. 
이는, 상용구 DB와 연계된 기능으로 대부분의 일본어 상용구 DB는 open source 이며, 
조만간에 최신의 것을 적용할 예정으로 있습니다. 
더 좋은 기능을 가지고 돌아 오겠습니다. 
감사합니다.
