+## 🚀 Production Deployment (Mobile)
+
+### Distribution Flow
+
+```
+Development → EAS Build → App Store / Google Play → User Device
+```
+
+The mobile app is a **native application** that runs directly on the device. No Docker or server needed - users download it from the app stores.
+
+### Step 1: Setup Expo Account
+
+```bash
+# Install EAS CLI
+npm install -g eas-cli
+
+# Create account at https://expo.dev
+
+# Login
+eas login
+```
+
+### Step 2: Initialize EAS Project
+
+```bash
+cd frontend-mobile
+eas init
+```
+
+This generates a `projectId` - add it to `app.json`:
+```json
+"extra": {
+  "eas": {
+    "projectId": "your-project-id"
+  }
+}
+```
+
+### Step 3: Configure Credentials
+
+**Android (Google Play):**
+1. Create developer account ($25 one-time fee)
+2. Create project in Google Cloud Console
+3. Enable Play Developer API
+4. Download `google-service-account.json`
+5. Place in `frontend-mobile/` directory
+
+**iOS (App Store):**
+1. Join Apple Developer Program ($99/year)
+2. Create App ID in Apple Developer portal
+3. Generate certificates and provisioning profiles
+4. Update `eas.json` with your credentials
+
+### Step 4: Build for Production
+
+```bash
+# Android (Google Play)
+eas build --profile production --platform android
+
+# iOS (App Store)
+eas build --profile production --platform ios
+```
+
+### Step 5: Submit to Stores
+
+```bash
+# Submit to Google Play
+eas submit --profile production --platform android
+
+# Submit to App Store
+eas submit --profile production --platform ios
+```
+
+### OTA Updates (Without App Store Review)
+
+Push updates directly to users without going through store review:
+
+```bash
+# Install expo-updates
+npx expo install expo-updates
+
+# Send update
+eas update --branch production --message "Fix: improved search"
+```
+
+### Useful Commands
