Screenshots: Trace 1.2.0 / 截图版本:词迹 1.2.0
Open the Trace online version on a phone or desktop browser. GitHub Pages publishes the same pages used by the Android app whenever main is updated.
| Tool | Purpose | Standalone file |
|---|---|---|
| Idiom Trace | Filter four-character Chinese idioms by character, initial, final, and tone clues | idiom-trace/idiom-trace-offline.html |
| Word Trace | Filter 2–18 letter English words by gray, yellow, and green clues | word-trace/word-trace-offline-en.html |
| Equation Trace | Find 3–8 character arithmetic expressions for a target result using gray, yellow, and green clues | equation-trace/equation-trace-offline.html |
All three standalone pages contain their data and filtering logic in a single file and continue to work without a network connection.
Trace 1.2.1 provides:
- English, Simplified Chinese, and Traditional Chinese interfaces;
- System, Light, and Dark appearance modes;
- all three solvers, including the new arithmetic-expression generator, inside one app;
- Equation Trace expressions using
+,-,*, and/, direct per-tile clue entry, and searches with incomplete clue rows; - expression-only Equation Trace results and copied text, without an appended equals sign or target answer;
- compact phone layouts based on familiar productivity-tool patterns;
- three text-size options, optional transitions and haptic feedback;
- optional screen wake lock and resume-last-tool behavior;
- no account, ads, analytics, or network permission.
- Download the latest APK from Releases.
- Open the APK on an Android device.
- If Android asks, allow the current browser or file manager to install unknown apps.
- Choose Install, or Update when an older version is already present.
The minimum supported version is Android 6.0 (API 23).
Open android in Android Studio, or build from PowerShell:
cd android
.\gradlew.bat lintDebug assembleDebugThe build requires JDK 17 or later and Android SDK 36. The debug APK is written to:
android/app/build/outputs/apk/debug/app-debug.apk
If those tools are not installed locally, run Build Android APK / 构建 Android APK in GitHub Actions; version tags trigger it automatically.
