+# App Performance Monitoring & Analytics Setup Guide
+
+**Project:** LifeTimer  
+**Version:** 1.0.0  
+**Date:** 2026-01-03
+
+## Overview
+
+This guide covers setting up production-ready analytics and performance monitoring for the LifeTimer app. The current implementation includes a placeholder analytics service that needs to be replaced with a real analytics provider.
+
+## Recommended Solutions
+
+### 1. Firebase Analytics (Primary Recommendation)
+
+**Why Firebase Analytics?**
+- Free tier with generous limits
+- Seamless integration with Flutter
+- Real-time analytics
+- User properties and event tracking
+- Integration with Firebase Crashlytics
+- Works well with Supabase
+
+**Setup Steps:**
+
+#### Step 1: Add Dependencies
+
+Add to `pubspec.yaml`:
+```yaml
+dependencies:
+  firebase_core: ^2.24.2
+  firebase_analytics: ^10.7.4
+  firebase_crashlytics: ^3.4.9
+  firebase_performance: ^0.9.3+11
+```
+
+#### Step 2: Initialize Firebase
+
+Create `lib/bootstrap/firebase.dart`:
+```dart
+import 'package:firebase_core/firebase_core.dart';
+import 'package:firebase_analytics/firebase_analytics.dart';
+import 'package:firebase_crashlytics/firebase_crashlytics.dart';
+import 'package:firebase_performance/firebase_performance.dart';
+import 'package:flutter/foundation.dart';
+
+Future<void> initializeFirebase() async {
+  await Firebase.initializeApp();
+  
+  // Initialize Analytics
+  FirebaseAnalytics.instance.setAnalyticsCollectionEnabled(true);
+  
+  // Initialize Crashlytics
+  FlutterError.onError = (errorDetails) {
+    FirebaseCrashlytics.instance.recordFlutterFatalError(errorDetails);
+  };
+  PlatformDispatcher.instance.onError = (error, stack) {
+    FirebaseCrashlytics.instance.recordError(error, stack, fatal: true);
+    return true;
+  };
+  
+  // Initialize Performance Monitoring
+  await FirebasePerformance.instance.setPerformanceCollectionEnabled(true);
+}
+```
+
+Update `lib/bootstrap/bootstrap.dart`:
+```dart
+Future<void> bootstrap() async {
+  WidgetsFlutterBinding.ensureInitialized();
+  
+  await initializeFirebase();
+  await Supabase.initialize(
+    url: Env.supabaseUrl,
+    anonKey: Env.supabaseAnonKey,
+  );
+  
+  initializeSupabaseClient();
+}
+```
+
+#### Step 3: Update Analytics Service
+
+Update `lib/core/services/analytics_service.dart`:
+```dart
+import 'package:firebase_analytics/firebase_analytics.dart';
+import 'package:firebase_crashlytics/firebase_crashlytics.dart';
+
+class AnalyticsService {
+  static final AnalyticsService _instance = AnalyticsService._internal();
+  factory AnalyticsService() => _instance;
+  AnalyticsService._internal();
+
+  final FirebaseAnalytics _analytics = FirebaseAnalytics.instance;
+  final FirebaseCrashlytics _crashlytics = FirebaseCrashlytics.instance;
+
+  bool _isInitialized = false;
+
+  Future<void> initialize() async {
+    _isInitialized = true;
+    await _analytics.setAnalyticsCollectionEnabled(true);
+  }
+
+  void setUserId(String userId) {
+    _analytics.setUserId(id: userId);
+  }
+
+  void setUserProperty(String name, dynamic value) {
+    _analytics.setUserProperty(name: name, value: value.toString());
+  }
+
+  void logEvent(String eventName, {Map<String, dynamic>? parameters}) {
+    _analytics.logEvent(
+      name: eventName,
+      parameters: parameters?.map(
+        (key, value) => MapEntry(key, value.toString()),
+      ),
+    );
+  }
+
+  void logSignUp({required String method}) {
+    _analytics.logSignUp(signUpMethod: method);
+  }
+
+  void logSignIn({required String method}) {
+    _analytics.logLogin(loginMethod: method);
+  }
+
+  void logSignOut() {
+    // Firebase doesn't have a built-in sign out event
+    logEvent('sign_out');
+  }
+
+  void logGoalCreated({required String goalId, required String hasLocation, required String hasImage}) {
+    logEvent('goal_created', parameters: {
+      'goal_id': goalId,
+      'has_location': hasLocation,
+      'has_image': hasImage,
+    });
+  }
+
+  void logGoalUpdated({required String goalId}) {
+    logEvent('goal_updated', parameters: {'goal_id': goalId});
+  }
+
+  void logGoalCompleted({required String goalId, required int daysInChallenge}) {
+    logEvent('goal_completed', parameters: {
+      'goal_id': goalId,
+      'days_in_challenge': daysInChallenge,
+    });
+  }
+
+  void logGoalDeleted({required String goalId}) {
+    logEvent('goal_deleted', parameters: {'goal_id': goalId});
+  }
+
+  void logCountdownStarted({required String startDate, required String endDate}) {
+    logEvent('countdown_started', parameters: {
+      'start_date': startDate,
+      'end_date': endDate,
+    });
+  }
+
+  void logCountdownViewed() {
+    _analytics.logScreenView(screenName: 'home_countdown');
+  }
+
+  void logProfileUpdated({required String fieldsUpdated}) {
+    logEvent('profile_updated', parameters: {
+      'fields_updated': fieldsUpdated,
+    });
+  }
+
+  void logProfileVisibilityChanged({required bool isPublic}) {
+    logEvent('profile_visibility_changed', parameters: {
+      'is_public': isPublic,
+    });
+  }
+
+  void logOnboardingCompleted() {
+    logEvent('onboarding_completed');
+  }
+
+  void logOnboardingStepCompleted({required String stepName}) {
+    logEvent('onboarding_step_completed', parameters: {
+      'step_name': stepName,
+    });
+  }
+
+  void logSettingsChanged({required String settingName, required String value}) {
+    logEvent('settings_changed', parameters: {
+      'setting_name': settingName,
+      'value': value,
+    });
+  }
+
+  void logNotificationEnabled({required String notificationType}) {
+    logEvent('notification_enabled', parameters: {
+      'notification_type': notificationType,
+    });
+  }
+
+  void logNotificationDisabled({required String notificationType}) {
+    logEvent('notification_disabled', parameters: {
+      'notification_type': notificationType,
+    });
+  }
+
+  void logError({required String error, String? context}) {
+    _crashlytics.recordError(
+      error,
+      null,
+      fatal: false,
+      information: context != null ? [context] : null,
+    );
+  }
+
+  void logScreenView({required String screenName}) {
+    _analytics.logScreenView(screenName: screenName);
+  }
+
+  void reset() {
+    _analytics.resetAnalyticsData();
+  }
+}
+```
+
+#### Step 4: Configure Firebase Console
+
+1. Go to [Firebase Console](https://console.firebase.google.com/)
+2. Create a new project: "LifeTimer"
+3. Add Android app:
+   - Package name: `com.lifetimer.app`
+   - Download `google-services.json`
+   - Place in `android/app/`
+4. Add iOS app:
+   - Bundle ID: `com.lifetimer.app`
+   - Download `GoogleService-Info.plist`
+   - Place in `ios/Runner/`
+
+#### Step 5: Configure Android
+
+Update `android/build.gradle`:
+```gradle
+buildscript {
+    dependencies {
+        classpath 'com.google.gms:google-services:4.4.0'
+    }
+}
+```
+
+Update `android/app/build.gradle`:
+```gradle
+apply plugin: 'com.google.gms.google-services'
+```
+
+#### Step 6: Configure iOS
+
+Update `ios/Runner/Info.plist`:
+```xml
+<key>FirebaseAppDelegateProxyEnabled</key>
+<false/>
+```
+
+### 2. Alternative: Mixpanel Analytics
+
+**Why Mixpanel?**
+- Advanced user segmentation
+- Funnel analysis
+- Cohort analysis
+- Real-time insights
+
+**Setup Steps:**
+
+Add to `pubspec.yaml`:
+```yaml
+dependencies:
+  mixpanel_flutter: ^2.2.0
+```
+
+Initialize in `lib/bootstrap/bootstrap.dart`:
+```dart
+import 'package:mixpanel_flutter/mixpanel_flutter.dart';
+
+Future<void> initializeMixpanel() async {
+  final mixpanel = await Mixpanel.init('YOUR_MIXPANEL_TOKEN');
+  mixpanel.track('app_opened');
+}
+```
+
+### 3. Alternative: Sentry (Error Tracking)
+
+**Why Sentry?**
+- Excellent error tracking
+- Performance monitoring
+- Release tracking
+- Breadcrumbs
+
+**Setup Steps:**
+
+Add to `pubspec.yaml`:
+```yaml
+dependencies:
+  sentry_flutter: ^7.14.0
+```
+
+Initialize in `lib/bootstrap/bootstrap.dart`:
+```dart
+import 'package:sentry_flutter/sentry_flutter.dart';
+
+Future<void> initializeSentry() async {
+  await SentryFlutter.init(
+    (options) {
+      options.dsn = 'YOUR_SENTRY_DSN';
+      options.tracesSampleRate = 1.0;
+      options.profilesSampleRate = 1.0;
+    },
+  );
+}
+```
+

+
+## Logging Framework
+
+Replace `print()` statements with proper logging:
+
+Add to `pubspec.yaml`:
+```yaml
+dependencies:
+  logger: ^2.0.2+1
+```
+
+Create `lib/core/utils/logger.dart`:
+```dart
+import 'package:logger/logger.dart';
+
+final logger = Logger(
+  printer: PrettyPrinter(
+    methodCount: 2,
+    errorMethodCount: 8,
+    lineLength: 120,
+    colors: true,
+    printEmojis: true,
+    printTime: true,
+  ),
+);
+
+final loggerNoStack = Logger(
+  printer: PrettyPrinter(
+    methodCount: 0,
+    errorMethodCount: 0,
+    lineLength: 120,
+    colors: true,
+    printEmojis: true,
+    printTime: true,
+  ),
+);
+```
+
+Usage:
+```dart
+// Instead of print('Analytics not initialized');
+logger.w('Analytics not initialized');
+
+// Instead of print('Analytics Event: $eventData');
+logger.d('Analytics Event: $eventData');
+
+// For errors
+logger.e('Error syncing mutation', error: e, stackTrace: stackTrace);
+```
+
+## Privacy & Compliance
+
+### Data Collection
+- Only collect necessary data
+- Anonymize user IDs where possible
+- Provide opt-out options
+- Follow GDPR and CCPA guidelines
+
+### User Consent
+- Add consent dialog on first launch
+- Allow users to opt out of analytics
+- Provide privacy policy link
+- Implement data deletion on request
+
+### Firebase Configuration
+```dart
+// Disable analytics collection for users who opt out
+await FirebaseAnalytics.instance.setAnalyticsCollectionEnabled(false);
+
+// Delete user data on account deletion
+await FirebaseAnalytics.instance.resetAnalyticsData();
+```
+
+## Testing Analytics
+
+### Local Testing
+1. Use Firebase DebugView for real-time event verification
+2. Test all event tracking flows
+3. Verify user properties are set correctly
+4. Test error reporting
+
+### DebugView Setup
+```dart
+// Enable DebugView for development
+await FirebaseAnalytics.instance.setAnalyticsCollectionEnabled(true);
+```
+
+### Event Verification
+```dart
