-## Project Overview
-FitAI is a fitness management solution with admin web app and React Native mobile app for client management, payments, attendance tracking, and notifications.
-
-## Build/Test Commands
-This project is in early prototype stage - no build system configured yet.
-- When implementing: expect standard npm/yarn commands (npm run dev, npm run build, npm test)
-- For single tests: use npm test -- --testNamePattern="test name" or npm test path/to/test.test.js
-
-## Code Style Guidelines
-- Use TypeScript for type safety
-- Follow React/React Native conventions
-- Use camelCase for variables and functions
-- Use PascalCase for components
-- Import order: external libraries → internal modules → relative imports
-- Implement proper error handling with try/catch blocks
-- Use semantic HTML and accessible components
-- Follow mobile-first responsive design principles
-- Implement proper state management (Context API or Redux)
-- Use environment variables for configuration
-- Write comprehensive tests for critical functionality

+# Authentication Migration Complete - Old Auth to Clerk
+
+**Date:** January 2025  
+**Status:** ✅ COMPLETED  
+**Migration Type:** Custom Auth → Clerk Authentication
+
+---
+
+## Overview
+
+The FitAI mobile app has been successfully migrated from a custom authentication system using `AuthContext` to **Clerk authentication**. All old authentication code has been removed and replaced with Clerk's robust, production-ready authentication platform.
+
+---
+
+## What Was Changed
+
+### ✅ Removed (Old Custom Auth)
+
+#### Files Deleted
+- ❌ `src/contexts/AuthContext.tsx` - Custom auth context provider
+- ❌ `src/app/login.tsx` - Old login screen
+- ❌ `src/app/register.tsx` - Old registration screen
+- ❌ `src/app/login/` - Old login directory
+- ❌ `src/app/register/` - Old register directory
+
+#### Old Auth Features (Removed)
+- Custom JWT/token management
+- Manual password hashing with bcrypt
+- Custom session management
+- Manual email validation
+- Custom user state management
+- SecureStore direct manipulation
+
+---
+
+### ✅ Added (Clerk Authentication)
+
+#### New Files Created

+- ✅ `src/app/(auth)/sign-up.tsx` - Clerk-powered sign-up with email verification
+- ✅ `src/app/(auth)/_layout.tsx` - Auth screen layout
+- ✅ `src/app/_layout.tsx` - ClerkProvider wrapper
+
+#### Updated Files
+- ✅ `src/hooks/useRequireAuth.ts` - Now uses Clerk hooks
+- ✅ `src/app/(tabs)/index.tsx` - Uses Clerk user data
+- ✅ `src/app/(tabs)/profile.tsx` - Uses Clerk user data
+- ✅ `src/app/(tabs)/_layout.tsx` - Clerk auth protection
+
+#### New Clerk Features
+- ✅ Email/password authentication
+- ✅ Email verification with codes
+- ✅ Secure token caching with expo-secure-store
+- ✅ Session management
+- ✅ Protected routes
+- ✅ User profile management
+- ✅ Sign-out functionality

+
+---
+
+## Code Migration Examples
+
+### Before (Old Custom Auth)
+
+```typescript
+// Old: Using custom AuthContext
+import { useAuth } from '@/contexts/AuthContext'
+
+export function useRequireAuth() {
+  const { user, isLoading } = useAuth()
+  const router = useRouter()
+
+  useEffect(() => {
+    if (!isLoading && !user) {
+      router.replace('/login')
+    }
+  }, [user, isLoading, router])
+
+  return { user, isLoading }
+}
+```
+
+### After (Clerk)
+
+```typescript
+// New: Using Clerk hooks
+import { useAuth, useUser } from "@clerk/clerk-expo"
+
+export function useRequireAuth() {
+  const { isLoaded, isSignedIn } = useAuth()
+  const { user } = useUser()
+  const router = useRouter()
+
+  useEffect(() => {
+    if (!isLoaded) return
+    
+    if (!isSignedIn && !inAuthGroup) {
+      router.replace("/(auth)/sign-in")
+    }
+  }, [isSignedIn, isLoaded, segments])
+
+  return { user, isLoading: !isLoaded, isSignedIn }
+}
+```
+
+---
+
+## Authentication Flow Changes
+
+### Old Flow
+```
+User opens app
+    ↓
+Check SecureStore for user data
+    ↓
+Parse JSON and validate
+    ↓
+Manual token refresh logic
+    ↓
+Redirect if invalid
+    ↓
+Custom login screen with form
+    ↓
+POST to /api/auth/login
+    ↓
+Store response in SecureStore
+    ↓
+Navigate to tabs
+```
+
+### New Flow (Clerk)
+```
+User opens app
+    ↓
+ClerkProvider initializes
+    ↓
+Check auth state (automatic)
+    ↓
+Not signed in?
+    ↓
+Show /(auth)/sign-in screen
+    ↓
+User signs in with Clerk
+    ↓
+Email verification (if new user)
+    ↓
+Clerk handles token management
+    ↓
+Navigate to /(tabs)
+    ↓
+All routes protected automatically
+```

+Not authenticated? → Redirect to Clerk hosted sign-in
+    ↓
+User signs in/up
+    ↓
+Clerk creates session
+    ↓
+Redirect to dashboard
+    ↓
+User can access protected routes
+```
+
+### Mobile App Flow
+
+```
+App launches
+    ↓
+ClerkProvider initializes
+    ↓
+Check auth state in TabLayout
+    ↓
+Not authenticated? → Redirect to /(auth)/sign-in
+    ↓
+User signs in or navigates to sign-up
+    ↓
+Email verification (for sign-up)
+    ↓
+Clerk creates session
+    ↓
+Redirect to /(tabs)

+---
+
+## 2. Admin App Setup (Next.js)
+
+### Step 1: Install Dependencies
+
+The Clerk package is already installed. Verify with:
+
+```bash
+cd apps/admin
+npm list @clerk/nextjs
+```
+
+### Step 2: Create Environment Variables
+
+1. Create a `.env.local` file in `apps/admin/`:
+
+```bash
+cd apps/admin
+cp .env.local.example .env.local
+```
+
+2. Edit `.env.local` and add your Clerk keys:
+
+```env
+# Clerk Authentication
+NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_YOUR_PUBLISHABLE_KEY_HERE
+CLERK_SECRET_KEY=sk_test_YOUR_SECRET_KEY_HERE
+
+# Clerk URLs
+NEXT_PUBLIC_CLERK_SIGN_IN_URL=/sign-in
+NEXT_PUBLIC_CLERK_SIGN_UP_URL=/sign-up
+NEXT_PUBLIC_CLERK_AFTER_SIGN_IN_URL=/
+NEXT_PUBLIC_CLERK_AFTER_SIGN_UP_URL=/
+
+# Database
+DATABASE_URL=./data/fitai.db
+```
+
+### Step 3: Configure Clerk Dashboard (Admin App)
+
+In the Clerk Dashboard:
+
+1. Go to **"Application"** → **"Paths"**
+2. Set the following URLs:
+   - **Sign-in URL**: `/sign-in` (or use Clerk's hosted pages)
+   - **Sign-up URL**: `/sign-up` (or use Clerk's hosted pages)
+   - **Home URL**: `/`
+
+3. Go to **"Sessions"**
+   - Enable "Multi-session handling" if you want users to have multiple sessions
+   - Set session lifetime as needed (default: 7 days)
+
+### Step 4: Test the Admin App
+

+
+---
+
+## 3. Mobile App Setup (Expo)
+
+### Step 1: Install Dependencies
+
+The Clerk Expo package and required dependencies are already installed. Verify with:
+
+```bash
+cd apps/mobile
+npm list @clerk/clerk-expo expo-web-browser expo-auth-session expo-secure-store expo-crypto
+```
+
+**Note**: If you need to install manually:
+```bash
+npm install @clerk/clerk-expo expo-web-browser expo-auth-session expo-secure-store expo-crypto react-dom react-native-web
+```
+
+**All Required Clerk Dependencies:**
+- `@clerk/clerk-expo` - Core Clerk SDK
+- `expo-web-browser` - OAuth flows and browser interactions
+- `expo-auth-session` - SSO and authentication sessions

+
+```bash
+cd apps/mobile
+cp .env.example .env
+```
+
+2. Edit `.env` and add your Clerk publishable key:
+
+```env
+# Clerk Authentication
+EXPO_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_YOUR_PUBLISHABLE_KEY_HERE
+
+# API Configuration
+EXPO_PUBLIC_API_URL=http://localhost:3000/api
+
+# App Configuration
+EXPO_PUBLIC_APP_NAME=FitAI
+EXPO_PUBLIC_APP_VERSION=1.0.0
+```
+
+**Note**: For mobile apps, you only need the publishable key (not the secret key).
+
+### Step 3: Configure Clerk Dashboard (Mobile App)
+
+In the Clerk Dashboard:
+
+1. Go to **"Application"** → **"Mobile"**
+2. Add your app's package/bundle identifiers:
+   - **Android**: `com.fitai.mobile` (or your custom package name)
+   - **iOS**: `com.fitai.mobile` (or your custom bundle ID)
+
+3. Go to **"Email, Phone, Username"** settings:
+   - Enable **Email address** as a required identifier
+   - Enable **Password** as a required authentication strategy
+   - Optional: Enable **Email verification code** for passwordless login
+
+### Step 4: Update App Configuration
+
+Edit `apps/mobile/app.json` to ensure your package names match Clerk configuration:
+
+```json
+{
+  "expo": {
+    "name": "FitAI",
+    "slug": "fitai-mobile",
+    "version": "1.0.0",
+    "ios": {
+      "bundleIdentifier": "com.fitai.mobile"
+    },
+    "android": {
+      "package": "com.fitai.mobile"
+    }
+  }
+}
+```
+
+### Step 5: Test the Mobile App
+
+```bash
+cd apps/mobile
+npm start
+```
+
+Use Expo Go to scan the QR code and test the app on your device.

+
+---
+
+## 5. Troubleshooting
+
+### Common Issues and Solutions
+
+#### Issue: "Missing Clerk Publishable Key"
+
+**Solution**: 
+- Ensure your `.env.local` (admin) or `.env` (mobile) file exists
+- Verify the key starts with `pk_test_` or `pk_live_`
+- Restart your development server after adding the key
+
+#### Issue: "Invalid API key"
+
+**Solution**:
+- Double-check your keys in the Clerk Dashboard
+- Make sure you're using the correct environment (test vs. production)
+- Ensure there are no extra spaces or quotes in your `.env` file
+
+#### Issue: Mobile app shows blank screen
+
+**Solution**:
+- Check the console logs for errors
+- Verify `@clerk/clerk-expo` is installed correctly
+- Ensure `expo-secure-store` is installed (required for token storage)
+- Ensure `expo-web-browser` is installed (required for OAuth flows)
+- Try clearing Expo cache: `npx expo start -c`
+
+#### Issue: "Unable to resolve expo-web-browser", "expo-auth-session", or "react-dom"
+
+**Solution**:
+Install all required Clerk dependencies at once:
+```bash
+cd apps/mobile
+npm install expo-web-browser expo-auth-session expo-secure-store expo-crypto react-dom react-native-web
+npx expo start -c
+```
+
+These packages are required by Clerk for:
+- `expo-web-browser` - OAuth authentication flows
+- `expo-auth-session` - SSO and session management
+- `expo-secure-store` - Secure token storage
+- `expo-crypto` - Cryptographic operations
+- `react-dom` - React DOM for web compatibility
+- `react-native-web` - React Native web compatibility layer
+
+#### Issue: Email verification code not received
+
+**Solution**:

+
+**Solution**:
+- Check your middleware configuration in `apps/admin/src/middleware.ts`
+- Ensure public routes are properly defined
+- Verify `NEXT_PUBLIC_CLERK_SIGN_IN_URL` is set correctly
+- Clear browser cookies and try again
+
+#### Issue: "ERESOLVE" errors during npm install
+
+**Solution**:
+- Use `--legacy-peer-deps` flag:
+  ```bash
+  npm install --legacy-peer-deps
+  ```
+- This is normal for React Native projects with multiple dependencies
+
+#### Issue: Bundling failed with Clerk dependencies
+
+**Solution**:

+  npm list @clerk/clerk-expo
+  ```
+
+---
+
+## Advanced Configuration
+
+### Customizing Clerk UI
+
+You can customize Clerk's appearance in both apps:
+
+**Admin App** (`apps/admin/src/app/layout.tsx`):
+```tsx
+<ClerkProvider
+  appearance={{
+    baseTheme: "light",
+    variables: {
+      colorPrimary: "#2563eb",
+      fontFamily: "Inter, sans-serif",
+    },
+  }}
+>
+```
+
+**Mobile App**: Use custom screens (already implemented in `apps/mobile/src/app/(auth)/`)
+
+### Adding Social Providers
+
+1. In Clerk Dashboard, go to **"Social Connections"**
+2. Enable providers (Google, Facebook, etc.)
+3. Add OAuth credentials for each provider
+4. No code changes needed - Clerk handles it automatically!
+
+### Webhooks (Optional)
+
+To sync Clerk users with your database:
+
+1. In Clerk Dashboard, go to **"Webhooks"**
+2. Add endpoint: `https://your-domain.com/api/webhooks/clerk`
+3. Select events: `user.created`, `user.updated`, `user.deleted`
+4. Implement webhook handler in `apps/admin/src/app/api/webhooks/clerk/route.ts`
+
+### Multi-tenant Support
