Offline document organizer for Android. No cloud. No background processes you didn't ask for. Your files stay on your device.
myOrganizer has three tools:
Pick a folder → the app reads filenames and document content → classifies each file into your custom categories using keyword matching → renames files with a consistent format ([CAT]_YYYYMMDD_originalname) → you review every move before anything is applied.
Pick a folder or select files → the app groups by size, then by MD5 hash → shows you exact duplicates → pre-selects all but the most recent copy → you confirm what to delete.
Define your own categories (e.g. WRK, INV, MED) with keywords. The Smart Organizer uses these to classify your documents. Files that don't match any category go to a [TO_REVIEW]/ folder for manual inspection.
- 100% offline — no network requests, no analytics, no telemetry
- All processing happens on-device
- Storage: AsyncStorage (local only)
- No permissions requested beyond file access for the folders you explicitly pick
Requirements: Node.js 20+, Android SDK, JDK 17+
cd frontend
npm install
npx expo prebuild --platform androidFor a release APK you need a signing keystore. Create frontend/android/keystore.properties:
storeFile=your-keystore.jks
storePassword=your-password
keyAlias=your-alias
keyPassword=your-passwordThen build:
cd frontend/android
./gradlew assembleReleaseOutput: frontend/android/app/build/outputs/apk/release/app-release.apk
CMake note (Windows): the React Native native build requires CMake 3.28+ to avoid the Windows 260-character path limit. Install from cmake.org and add
cmake.dir=C\:\\path\\to\\cmaketofrontend/android/local.properties.
