RakuRaku IME

RakuRaku IME is a modern rebuild of the classic EZ Input Method (輕鬆輸入法)

for Android, built with Jetpack Compose and Room. Type Traditional Chinese

using 高衡緒's shape-based radical system, with a live candidate bar and

near-instant prefix matching powered by a full-text-search dictionary that

ships pre-packaged inside the app — no initial download required.

Features

* Full EZ radical layout with phrase composing rules.

* English word prediction backed by the Google 10K common-word corpus.

* Emoji keyboard with eight categories and 1,184 emojis.

* Dialer-style number pad.

* Split keyboard in landscape, adjustable height, optional keypress vibration.

* Material You theming on Android 12+, with a Solarized fallback on older

devices or by user choice.

* Traditional Chinese (臺灣) and English UI; per-app language picker on

Android 13+.

* Fully offline — no network access, no analytics, no tracking. Your

keystrokes never leave the device.
