+## 📱 Mobile App Setup (React Native)
+
+### Prerequisites
+
+- Node.js (v18 or higher)
+- npm or yarn
+- **Expo CLI**: `npm install -g expo-cli`
+- **EAS CLI**: `npm install -g eas-cli`
+- **iOS**: Xcode (Mac only) + CocoaPods
+- **Android**: Android Studio + Android SDK
+
+### Quick Start
+
+```bash
+# Install all dependencies (backend + web + mobile)
+npm run install:all
+
+# Start mobile development server
+npm run dev:mobile
+
+# Scan QR code with Expo Go app (iOS/Android)
+```
+
+### Development Build
+
+For native features (camera, biometrics, notifications), use a development build:
+
+```bash
+# Install EAS CLI
+npm install -g eas-cli
+
+# Login to Expo
+eas login
+
+# Create development build
+eas build --profile development --platform ios
+eas build --profile development --platform android
+```

+└── types/                  # TypeScript types
+```
+
+### Native Features
+
+| Feature | Implementation |
+|---------|---------------|
+| Barcode Scanner | `expo-camera` with `CameraView` |
+| Push Notifications | `expo-notifications` |
+| Biometrics | `expo-local-authentication` |
+| Maps | `react-native-maps` |
+| Secure Storage | `expo-secure-store` |
+
+### EAS Build Profiles
+
+| Profile | Platform | Build Type | Use Case |
+|---------|----------|------------|----------|
+| `development` | iOS | Simulator | Local testing on Mac |
+| `development` | Android | APK | Local testing on device |
+| `preview` | Android | APK | Internal testing & sharing |
+| `production` | Android | AAB | Google Play Store submission |
+
+**Note:** iOS builds require Apple Developer account ($99/year) and are configured separately.
+
+### Environment Configuration
+
+The mobile app uses the same backend API as the web app. Configure the API URL in:
+
+```typescript
+// frontend-mobile/constants/config.ts
+const ENV = {
+  development: {
+    API_BASE_URL: 'http://localhost:3001/api',
+  },
+  production: {
+    API_BASE_URL: 'https://your-production-api.com/api',
+  },
+};
+```
+
+## 🚀 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
+
+| Command | Description |
+|---------|-------------|
+| `eas build:list` | View previous builds |
+| `eas build:cancel <id>` | Cancel a build |
+| `eas submit:list` | View previous submissions |
+| `eas update` | Send OTA update |

+# Diseño: Acceso al Panel de Administración
+
+## Resumen
+Añadir un botón de acceso al panel de administración en la página de perfil (pestaña "Usuario") que solo sea visible para usuarios con permisos de administrador.
+
+## Objetivo
+Proporcionar una forma intuitiva y consistente para que los usuarios administradores accedan al panel de administración desde la interfaz principal.
+
+## Requisitos
+1. El botón solo debe aparecer cuando el usuario tiene `is_admin: true`
+2. El botón debe seguir el mismo estilo que los otros elementos del menú del perfil
+3. Al hacer clic, debe navegar a la vista de administración existente
+4. No debe afectar la experiencia de usuarios no administradores
+
+## Diseño Detallado
+
+### Ubicación
+- **Página:** ProfileView (pestaña "Usuario" en BottomNav)
+- **Sección:** Dentro de `.profile-menu`, después de "Configuración de Texto"
+- **Posición:** Antes del botón "Cerrar Sesión"
+
+### Componente
+- **Tipo:** Botón con ícono, texto y chevron (igual que otros items del menú)
+- **Ícono:** Engranaje (⚙️) con fondo de color primario
+- **Texto:** "Panel de Administración"
+- **Estilo:** Idéntico a `.profile-menu-item` existente
+
+### Comportamiento
+1. **Renderizado condicional:**
+   ```jsx
+   {currentUser?.is_admin && (
+     <button className="profile-menu-item" onClick={onAdminClick}>
+       <div className="menu-item-icon menu-item-icon--primary">
+         <svg>...</svg>
+       </div>
+       <span className="menu-item-label">Panel de Administración</span>
+       <svg className="menu-item-chevron">...</svg>
+     </button>
+   )}
+   ```
+
+2. **Navegación:**
+   - Recibir función `onAdminClick` como prop
+   - En `App.jsx`, implementar `handleAdminClick` que cambie `screen` a `'admin'`
+
+### Cambios en Archivos
+
+#### 1. `frontend/src/views/ProfileView.jsx`
+- Añadir prop `onAdminClick`
+- Renderizar botón condicionalmente basado en `currentUser?.is_admin`
+
+#### 2. `frontend/src/App.jsx`
+- Añadir función `handleAdminClick` que establezca `screen` en `'admin'`
+- Pasar `onAdminClick={handleAdminClick}` a `ProfileView`
+
+### Estilos
+No se requieren cambios en CSS - se reutilizan las clases existentes:
+- `.profile-menu-item`
+- `.menu-item-icon--primary`
+- `.menu-item-label`
+- `.menu-item-chevron`
+
+## Criterios de Aceptación
+1. ✅ Botón visible solo para usuarios admin
+2. ✅ Botón no visible para usuarios normales
+3. ✅ Estilo consistente con otros elementos del menú
+4. ✅ Al hacer clic, navega a la vista de administración
+5. ✅ No se muestra en dispositivos móviles si el usuario no es admin
+
+## Impacto
+- **Archivos modificados:** 2 (`ProfileView.jsx`, `App.jsx`)
+- **Complejidad:** Baja
+- **Riesgo:** Mínimo - solo añade un elemento condicional

+
+### 2.2 Stack Tecnológico
+
+| Componente | Tecnología | Justificación |
+|------------|------------|---------------|
+| Framework | Expo SDK 52+ | Setup rápido, OTA updates, fácil publicación |
+| Routing | Expo Router v4 | File-based routing, similar a Next.js |
+| Navegación | React Navigation | Bottom tabs + stack navigation |
+| State | Zustand | Ligero, sin boilerplate, fácil de usar |
+| HTTP Client | Axios | Interceptors, cancelación de requests |
+| Cache | TanStack Query | Cache automático, optimistic updates |
+| Mapas | react-native-maps | Google Maps provider nativo |
+| Barcode | expo-camera | Escaneo de código de barras nativo |
+| Storage | AsyncStorage + expo-secure-store | Datos offline + tokens seguros |
+| Animaciones | React Native Reanimated 3 | Animaciones fluidas en 60fps |
+
+---
+
+## 3. Estructura de Navegación
+
+### 3.1 Navegación Principal
+
+```
+Bottom Tabs
+├── Home (🔍)        → Búsqueda de medicamentos
+├── Mapa (📍)        → Mapa de farmacias
+└── Perfil (👤)      → Perfil de usuario + Admin
+```
+
+### 3.2 Navegación Detallada
+
+```
+Home Tab (Stack)
+├── index.tsx         ← Lista de resultados de búsqueda
+└── medicine/[id].tsx ← Detalle de medicamento
+
+Mapa Tab (Stack)
+├── map.tsx           ← Mapa con marcadores de farmacias
+└── pharmacy/[id].tsx ← Detalle de farmacia
+
+Perfil Tab (Stack)
+├── profile.tsx       ← Info de usuario + opciones
+├── auth/login.tsx    ← Login (si no autenticado)
+├── auth/register.tsx ← Registro
+└── admin/            ← Panel admin (solo si auth + admin)
+```
+
+### 3.3 Flujos de Navegación
+
+- **Auth Flow**: Si no hay token → redirigir a login
+- **Admin Flow**: Si usuario es admin → mostrar acceso a admin
+- **Deep Linking**: URLs como `farmafinder://medicine/123` abren pantalla específica
+
+---
+
+## 4. Funcionalidades
+
+### 4.1 MVP (Paridad con Web)
+
+| Funcionalidad | Descripción |
+|---------------|-------------|
+| **Búsqueda** | Búsqueda en tiempo real de medicamentos vía API CIMA |
+| **Resultados** | Lista de resultados con nombre, principio activo |
+| **Detalle medicamento** | Precio, stock, farmacias que lo tienen |
+| **Mapa farmacias** | Marcadores en mapa con ubicación |
+| **Detalle farmacia** | Dirección, teléfono, medicamentos disponibles |
+| **Auth** | Login/registro de usuarios |
+
+### 4.2 Extras Nativos (NUEVO)
+
+| Funcionalidad | Descripción |
+|---------------|-------------|
+| **Push Notifications** | Alertas de disponibilidad de medicamentos favoritos |

+
+---
+
+## 5. Integración con la API
+
+### 5.1 Cliente API
+
+```typescript
+// frontend-mobile/services/api.ts
+import axios from 'axios';
+
+const API_BASE = __DEV__ 
+  ? 'http://localhost:3001/api' 
+  : 'https://tu-dominio.com/api';
+
+export const api = axios.create({
+  baseURL: API_BASE,
+  timeout: 10000,
+  headers: { 'Content-Type': 'application/json' }
+});
+
+// Request interceptor para auth token
+api.interceptors.request.use((config) => {
+  const token = getToken();
+  if (token) config.headers.Authorization = `Bearer ${token}`;
+  return config;
+});
+```
+
+### 5.2 Endpoints
+
+**Públicos:**
+- `GET /api/medicines/search?q=<query>` - Búsqueda de medicamentos
+- `GET /api/medicines/:nregistro` - Detalle de medicamento
+- `GET /api/medicines/:nregistro/pharmacies` - Farmacias con medicamento
+- `GET /api/pharmacies` - Todas las farmacias
+
+**Autenticados:**
+- `POST /api/auth/login` - Login
+- `POST /api/auth/logout` - Logout
+- `GET /api/auth/check` - Verificar auth
+
+**Admin:**
+- CRUD de farmacias
+- Búsqueda de medicamentos para admin
+- Vincular medicamentos a farmacias
+
+### 5.3 Estrategia de Cache
+
+```typescript
+// Con TanStack Query
+const { data, isLoading } = useQuery({
+  queryKey: ['medicines', searchQuery],
+  queryFn: () => searchMedicines(searchQuery),
+  staleTime: 5 * 60 * 1000, // 5 minutos
+  cacheTime: 30 * 60 * 1000, // 30 minutos
+});
+```
+
+**Persistencia offline:**
+- AsyncStorage para datos no sensibles
+- expo-secure-store para tokens y credenciales
+- React Query persistor para cache de queries
+
+---
+
+## 6. Diseño Visual
+
+### 6.1 Design Tokens

+  sm: 8,
+  md: 16,
+  lg: 24,
+  xl: 32,
+};
+
+export const borderRadius = {
+  sm: 8,
+  md: 12,
+  lg: 16,
+};
+```
+
+### 6.2 Componentes Principales
+
+| Componente | Descripción |
+|------------|-------------|
+| **SearchBar** | Input con debounce (300ms) + dropdown de resultados |
+| **MedicineCard** | Card con nombre, principio activo, precio, badge de stock |
+| **PharmacyMarker** | Marcador personalizado en mapa con info window |
+| **StockBadge** | Badge verde (disponible) / rojo (sin stock) |
+| **LoadingSpinner** | Spinner nativo durante cargas |
