+# tallyflow-decode Review
+
+**Tech Stack:** Flutter (mobile app for iOS/Android)
+
+## Purpose
+Mobile application for decoding and interacting with TallyFlow tags/assets.
+
+## Key Directories
+- `lib/`: Main Dart/Flutter source
+- `android/` & `ios/`: Platform-specific code
+- `assets/`, `store_listing/`: App store assets and metadata
+
+## Observations
+- Companion mobile app to the TallyFlow platform
+- Likely handles on-device scanning, decoding, and sync with the backend
+- Has build scripts for debug/release and clean
+- APP_STORE.md and store_listing suggest it's published or prepared for app stores
+
+## Relevance
+- Mobile capture layer (asset scanning, tag reading)
+- Complements tallyflow-web and tallyflow-iot
+
+## Status
+Initial file structure review complete. Next: inspect pubspec.yaml and lib/ for specific features.
