+# Future Improvements for RevenueCat Integration
+
+This document tracks potential improvements for the RevenueCat integration that are not critical but would enhance code quality and maintainability.
+
+## Code Quality Enhancements
+
+### 1. Dependency Injection Consistency
+
+**Current State:** The RevenueCatService uses callbacks for some values but direct access for others.
+
+**Issue:** 
+- Uses `getDailyCommandLimit()` callback ✅
+- Uses `isPurchasedNotifier.value` directly ⚠️
+- Checks `isTrialExpired` and `Platform.isAndroid` directly ⚠️
+
+**Proposed Improvement:**
+```dart
+// Add more callbacks for complete DI pattern
+RevenueCatService(
+  this._prefs, {
+  required this.isPurchasedNotifier,
+  required this.getDailyCommandLimit,
+  required this.setDailyCommandLimit,
+  required this.isAndroid,  // NEW
+});
+```
+
+**Priority:** Low - Current implementation works correctly
+
+**Effort:** Medium - Would require refactoring constructor and call sites
+
+---
+
+### 2. Magic Number for Android Command Limit
+
+**Current State:**
+```dart
+if (!isTrialExpired && Platform.isAndroid) {
+  setDailyCommandLimit(80);  // Hardcoded value
+}
+```
+
+**Issue:** The value `80` is hardcoded without explanation.
+
+**Proposed Improvement:**
+```dart
+// In RevenueCatService
+static const int androidTrialCommandLimit = 80;
+
+// Usage
+if (!isTrialExpired && Platform.isAndroid) {
+  setDailyCommandLimit(androidTrialCommandLimit);
+}
+```
+
+**Priority:** Low - Value is only used once, well-documented in context
+
+**Effort:** Trivial - Just extract to constant
+
+---
+
+### 3. Platform Detection Abstraction
+
+**Current State:**
+```dart
+if (!isTrialExpired && Platform.isAndroid) {
+  // Android-specific logic
+}
+```
+
+**Issue:** Direct platform checks could be abstracted for testability.
+
+**Proposed Improvement:**
+```dart
+// Pass platform info through DI
+final bool isAndroidPlatform;
+
+RevenueCatService(
+  this._prefs, {
+  // ... other params
+  this.isAndroidPlatform = kIsAndroid,  // Can be mocked in tests
+});
+```
+
+**Priority:** Very Low - Current approach is standard for Flutter
+
+**Effort:** Low - Simple parameter addition
+
+---
+
+## Feature Enhancements
+
+### 4. Subscription Support
+
+**Current State:** Only supports lifetime (non-consumable) purchases.
+
+**Proposed Addition:**
+- Monthly subscriptions
+- Annual subscriptions
+- Subscription status tracking
+- Expiration handling
+
+**Priority:** Medium - Depends on business requirements
+
+**Effort:** High - Requires:
+- RevenueCat offering configuration
+- UI updates for subscription display
+- Subscription renewal handling
+- Cancellation support
+
+---
+
+### 5. Analytics Integration
+
+**Current State:** No purchase analytics beyond logs.
+
+**Proposed Addition:**
+- Track purchase attempts
+- Monitor conversion rates
+- A/B test different offerings
+- Revenue analytics
+
+**Priority:** Low - Nice to have for business insights
+
+**Effort:** Medium - Requires analytics SDK integration
+
+---
+
+### 6. Promotional Offers
+
+**Current State:** No promotional offer support.
+
+**Proposed Addition:**
+- iOS promotional offers
+- Android promo codes
+- Limited-time discounts
+- First-purchase incentives
+
+**Priority:** Low - Marketing feature
+
+**Effort:** Medium - RevenueCat SDK supports this
+
+---
+
+## Testing Improvements
+
+### 7. Unit Tests for RevenueCat Service
+
+**Current State:** No unit tests for RevenueCat integration.
+
+**Proposed Addition:**
+```dart
+test('RevenueCatService initializes with valid API key', () async {
+  // Mock RevenueCat SDK
+  // Verify initialization
+});
+
+test('RevenueCatService falls back gracefully without API key', () async {
+  // Verify fallback behavior
+});
+```
+
+**Priority:** Medium - Would improve confidence in changes
+
+**Effort:** High - Requires mocking RevenueCat SDK
+
+---
+
+### 8. Integration Tests
+
+**Current State:** Manual testing only.
+
+**Proposed Addition:**
+- Automated purchase flow tests
+- Entitlement checking tests
+- Paywall presentation tests
+- Customer Center tests
+
+**Priority:** Medium - Would catch regressions
+
+**Effort:** Very High - Requires test environment setup
+
+---
+
+## Documentation Enhancements
+
+### 9. Video Tutorial
+
+**Current State:** Text documentation only.
+
+**Proposed Addition:**
+- Setup walkthrough video
+- RevenueCat dashboard configuration video
+- Build configuration demonstration
+
+**Priority:** Low - Text docs are comprehensive
+
+**Effort:** Medium - Recording and editing
+
+---
+
+### 10. Troubleshooting Flowchart
+
+**Current State:** Text-based troubleshooting.
+
+**Proposed Addition:**
+- Visual decision tree for common issues
+- Error code reference
+- Quick diagnosis guide
+
+**Priority:** Very Low - Current docs are clear
+
+**Effort:** Low - Create diagram
+
+---
+
+## Implementation Priority
+
+### High Priority (Do Soon)
+- None currently - all critical issues resolved
+
+### Medium Priority (Consider for Next Sprint)
+- Unit tests (#7)
+- Subscription support (#4) - if business needs it
+
+### Low Priority (Backlog)
+- Extract magic number (#2) - trivial, do if touching that code
+- Analytics integration (#5) - if product team requests
+- Dependency injection consistency (#1) - only if refactoring for other reasons
+
+### Very Low Priority (Optional)
+- Platform detection abstraction (#3)
+- Promotional offers (#6)
+- Video tutorial (#9)
+- Troubleshooting flowchart (#10)
+- Integration tests (#8) - high effort, moderate value
+
+---
+
+## Notes
+
+- Current implementation is **production-ready** as-is
+- These improvements are **optional enhancements**
+- Prioritize based on actual business/technical needs
+- Don't optimize prematurely - wait for real pain points
+
+## Decision Log
+
+**Why not implement these now?**
+
+1. **Time constraints** - Minimal change requirement
+2. **Working implementation** - No critical issues
+3. **YAGNI principle** - Don't add complexity until needed
+4. **Maintainability** - Simpler code is easier to maintain
+5. **Testing** - Manual testing sufficient for initial release
+
+**When to revisit?**
+
+- If adding subscriptions → Do #4, #5
+- If testing becomes pain point → Do #7, #8  
+- If code becomes hard to maintain → Do #1, #2, #3
+- If users need help → Do #9, #10
+- If new promotional campaigns → Do #6
