+# Mobile App
+
+Purpose: riding/offline companion.
+
+MVP mobile scope can be a placeholder until the web planner and backend are stable.
+
+Primary future screens:
+
+- Trip list.
+- Offline pack status.
+- Riding mode: next water/food/sleep/repair/bailout.
+- Map view.
+- Report issue.
+- Export/share route.
+
+Offline-critical data:
+
+- route geometry,
+- stages,
+- POIs,
+- rules,
+- exports,
+- report queue.
+
+## Implemented placeholder
+
+The current package is not a full React Native shell. It provides compiled TypeScript contracts for the future mobile app:
+
+- `OfflineReportQueue` for dated, location-bound reports captured without network access;
+- `OfflinePackIndex` for downloaded route/stage/POI/rule/export manifests;
+- storage abstraction that can later be backed by SQLite, AsyncStorage, or a native key-value store.
