Kuaizi IME is an efficient and fast Chinese Pinyin input method editor.
About this app
筷字输入法 (Kuaizi IME) is a system based on the combinatorial features of Chinese Pinyin. It is an efficient and fast input method editor, suitable for electronic touchscreen devices.
筷字输入法 (Kuaizi IME) abandones the traditional method of tapping on virtual keyboard keys one by one, it instead offers a swipe input method for Pinyin, combined with the combinatorial features of Pinyin letters. The key layout is designed to make Pinyin input more accurate and convenient.
筷字输入法 (Kuaizi IME) provides editing support such as cursor movement and text selection for the target editor, thereby eliminating the frustration of being unable to accurately position inputs and text due to the small screen size of mobile devices. This further enhances text input and editing efficiency on small-screen devices.
User-data generated by 筷字输入法 (Kuaizi IME) is stored locally. It does not connect to the internet and will not collect nor analyze user data or behavior habits. Furthermore, it does not support or provide predictive input nor fuzzy matching mechanisms. To some extent, this input method editor aims to enhance the users' ability to recognize and memorize Chinese characters and Pinyin, ensuring that the reliance on digital tools does not lead to the gradual forgetting and eventual abandonment of 「汉字」(Hànzì, Chinese characters), a treasure of Chinese civilization.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.crazydan.studio.app.ime.kuaizi is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 3.1.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Kuaizi IME first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Kuaizi IME, and a listing is removed when the evidence for it stops holding up.
