-请始终使用中文进行回复和编写文档。包括：
-
-- 所有对话回复都使用中文
-- 代码注释使用中文
-- 文档和说明使用中文

 - **Reset project**: `npm run reset-project`
 
 ## Architecture
-- **Framework**: React Native (Expo) with TypeScript.
-- **Navigation**: Expo Router for file-based routing (`app/` directory).
-- **State Management**: Redux Toolkit with slices for different domains (user, training plans, workouts, challenges, etc.).
-- **UI**: Themed components (`ThemedText`, `ThemedView`) and reusable UI elements (`Collapsible`, `ParallaxScrollView`).
-- **API Layer**: Service files for communicating with backend APIs (`services/` directory).
-- **Data Persistence**: AsyncStorage for local data storage.
-- **Platform-Specific**: Android (`android/`) and iOS (`ios/`) configurations with native modules.
-- **Hooks**: Custom hooks for color scheme (`useColorScheme`), theme management (`useThemeColor`), and Redux integration (`useRedux`).
-- **Dependencies**: React Navigation for tab-based navigation, Expo modules for native features (haptics, blur, image picking, etc.), and third-party libraries for specific functionality.
+- **Framework**: React Native (Expo) with TypeScript using Expo Router for file-based navigation
+- **State Management**: Redux Toolkit with domain-specific slices (`store/`) and typed hooks (`hooks/redux.ts`)
+- **Authentication**: Custom auth guard system with `useAuthGuard` hook for protected navigation
+- **Navigation**: 
+  - File-based routing in `app/` directory with nested layouts
+  - Tab-based navigation with custom styling and haptic feedback
+  - Route constants defined in `constants/Routes.ts`
+- **UI System**:
+  - Themed components (`ThemedText`, `ThemedView`) with color scheme support
+  - Custom icon system with `IconSymbol` component for iOS symbols
+  - Reusable UI components in `components/ui/`
+- **Data Layer**: 
+  - API services in `services/` directory with centralized API client
+  - AsyncStorage for local persistence
+  - Background task management for sync operations
+- **Native Integration**:
+  - Health data integration with HealthKit
+  - Apple Authentication
+  - Camera and photo library access for posture assessment
+  - Push notifications with background task support
+  - Haptic feedback integration
 
-## Key Features
-- **Authentication**: Login flow with Apple authentication support.
-- **Training Plans**: Creation and management of personalized pilates training plans.
-- **Workouts**: Daily workout tracking and session management.
-- **AI Features**: AI coach chat and posture assessment capabilities.
-- **Health Integration**: Integration with health data tracking.
-- **Content Management**: Article reading and educational content.
-- **Challenge System**: Challenge participation and progress tracking.
-- **User Profiles**: Personal information management and goal setting.
+## Key Architecture Patterns
+- **Redux Auto-sync**: Listener middleware automatically syncs checkin data changes to backend
+- **Type-safe Navigation**: Uses Expo Router with TypeScript for route type safety
+- **Authentication Flow**: `pushIfAuthedElseLogin` function handles auth-protected navigation
+- **Theme System**: Dynamic theming with light/dark mode support and color tokens
+- **Service Layer**: Centralized API client with interceptors and error handling
 
-## Directory Structure
-- `app/`: Main application screens and routing
-- `components/`: Reusable UI components
-- `constants/`: Application constants and configuration
-- `hooks/`: Custom React hooks
-- `services/`: API service layer
-- `store/`: Redux store and slices
-- `types/`: TypeScript type definitions

+## Development Conventions
+- Use absolute imports with `@/` prefix for all internal imports
+- Follow existing Redux slice patterns for state management
+- Implement auth guards using `useAuthGuard` hook for protected features
+- Use themed components for consistent styling
+- Follow established navigation patterns with typed routes
