icon 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.

WhatsNew:

- New: User Phrase Manager. Add, edit, search, and delete your
own phrases under Settings → User Phrase Manager. Your phrases
are always ranked ahead of the bundled corpus for matching
keystrokes, with an "Analyse Roots" button that derives the
canonical EZ keystrokes from the phrase length and per-char
encoding rules. Per-phrase use is tracked so frequently used
user phrases overtake older ones on the same prefix. CSV
backup / restore included.
