Trime (同文輸入法) is an Android input method built on the RIME input method framework, designed to support Chinese dialects, shape-based and phonetic-based input schemes on one platform. People use it when they want a highly configurable IME that goes beyond standard pinyin input, including support for Wubi, Cangjie, and various regional dialect input schemes.

Why isn’t Trime on Google Play?
Trime is published by its developer on GitHub and is also available on F-Droid. A Google Play listing exists as well, but this page offers the GitHub release directly for users who prefer it.
Is Trime safe?
Trime is open source under the GPL-3.0 license, and the download comes from the developer's official GitHub releases page. It is also distributed on F-Droid, which independently builds and verifies open source apps, so you can treat that as a trustworthy alternative source. As an input method app, Trime will ask for permission to act as your system keyboard, which is required for it to function. Trime comes straight from its developer rather than through Google Play, so it hasn’t gone through Google’s app review. As with any app, check the permissions it asks for and install it if you’re comfortable with them.
How to install
- Tap the download button above: the APK file downloads straight to your phone.
