-# Welcome to your Expo app 👋
+# SecureCam Mobile (Expo)
 
-This is an [Expo](https://expo.dev) project created with [`create-expo-app`](https://www.npmjs.com/package/create-expo-app).
+React Native mobile client for the SecureCam backend.
 
-## Get started
+## Features migrated from the Svelte web app
 
-1. Install dependencies
+- Email/password auth + account creation
+- Device onboarding (`camera` or `client` role)
+- Realtime socket connection status
+- Client dashboard:
+  - Link/unlink cameras
+  - Rename linked cameras
+  - Request live stream sessions
+  - View frame-based live feed fallback images
+  - Open recordings by presigned URL
+- Activity feed (motion notifications)
+- Settings (diagnostics + sign out)
+- Camera dashboard:
+  - Native camera preview (`expo-camera`)
+  - Frame relay over Socket.IO for stream fallback
+  - Motion start/end controls
 
-   ```bash
-   npm install
-   ```
+## Prerequisites
 
-2. Start the app
+- Node.js 20+
+- npm
+- Expo CLI via `npx expo ...`
+- Backend running on port `3000` (default)
 
-   ```bash
-   npx expo start
-   ```
+## Environment setup
 
-In the output, you'll find options to open the app in a
-
-- [development build](https://docs.expo.dev/develop/development-builds/introduction/)
-- [Android emulator](https://docs.expo.dev/workflow/android-studio-emulator/)
-- [iOS simulator](https://docs.expo.dev/workflow/ios-simulator/)
-- [Expo Go](https://expo.dev/go), a limited sandbox for trying out app development with Expo
-
-You can start developing by editing the files inside the **app** directory. This project uses [file-based routing](https://docs.expo.dev/router/introduction).
-
-## Get a fresh project
-
-When you're ready, run:
+Set the backend URL for the mobile app:
 
 ```bash
-npm run reset-project
+EXPO_PUBLIC_API_BASE_URL=http://<HOST>:3000
 ```
 
-This command will move the starter code to the **app-example** directory and create a blank **app** directory where you can start developing.
+You can place this in `MobileApp/.env`.

+```bash

+npm install
+npm run start
+```
+
+Then open via Expo Go / simulator.
+
+## Native module notes
+
+This app uses `expo-camera` for native camera preview and frame capture.
+
+If your environment is offline, dependency installation may fail. Once network is available, run:
+
+```bash
+cd MobileApp
+npx expo install expo-camera socket.io-client
+```
+
+## WebRTC note
+
+Current native mobile live viewing still uses the legacy `stream:frame` fallback path.
+
+The backend `SIMPLE_STREAMING` flag therefore defaults to `false` for safe rollout.
+
+For full native WebRTC publish/subscribe parity, add a supported RN WebRTC stack (for example `react-native-webrtc`) and replace frame relay with peer connection flows equivalent to the web client before enabling `SIMPLE_STREAMING` by default.
+
+## Verification
+
+```bash
+cd MobileApp
+npm run lint
+npx tsc --noEmit
+```
