+# GPS Speedometer - Claude Code Project Memory
+
+## Project Overview
+A customizable Flutter GPS speedometer app targeting Android devices, emphasizing modularity and user customization.
+
+## Current Status: v1.0 Complete 
+**Fully functional GPS speedometer with all core requirements implemented.**
+
+### Architecture Implemented
+- **State Management:** Provider pattern
+- **Structure:** Modular widgets, providers, screens separation
+- **Persistence:** SharedPreferences for settings
+- **GPS Service:** Geolocator with permission handling
+- **UI Patterns:** Consumer widgets, responsive design
+
+### Core Features Completed
+-  Real-time GPS speed tracking with accuracy monitoring
+-  Customizable speed units (km/h ” mph) with persistent storage
+-  Dual display styles: Digital speedometer + Analog gauge
+-  Dark/Light theme support with system integration
+-  Optional metrics panel: coordinates, distance, trip time, accuracy
+-  Trip reset functionality and comprehensive error handling
+-  Portrait orientation lock for mobile-first experience
+-  Android permissions configuration (FINE_LOCATION, COARSE_LOCATION)
+
+### Technical Stack
+```
+Dependencies: geolocator, permission_handler, provider, shared_preferences, flutter_material_color_picker
+Platforms: Android (primary), iOS support included but untested
+Architecture: Provider + Consumer pattern for reactive state management
+Permissions: Location services with graceful degradation
+```
+
+## TODO - Future Improvements =
+
+### UI/UX Enhancements
+- [ ] **Portrait/Landscape Support**: Automatic orientation detection (ignore system auto-rotate toggle)
+- [ ] **Interface Rearrangement**: User-defined layout customization
+- [ ] **Interactive Gauge**: Click gauge face to switch digital/analog modes
+- [ ] **Settings Menu Refurbishment**: More intuitive interactions and better UX
+
+### Technical Improvements  
+- [ ] **Font Embedding**: Consider custom fonts for better typography
+- [ ] **Feature Removal**: Identify and remove unused/redundant functionalities
+- [ ] **Code Cleanup**: Refactor deprecated warnings, optimize performance
+
+### Design Philosophy
+- Preserve modularity for easy future extensions
+- Prioritize user customization options
+- Maintain clean, extensible architecture
+- Focus on mobile-first, gesture-friendly interactions
+
+## Development Notes
+- **Testing**: Requires physical Android device for GPS functionality
+- **Build System**: Standard Flutter build process, first builds take time for Android SDK setup
+- **Memory**: Project uses automatic Claude Code memory - this file for major decisions only
+- **Git**: Active repository at `https://github.com/mikkelimatlock/gps_speedo`
+
+## Code Patterns to Maintain
+- Provider pattern for state management
+- Separate widgets for reusability  
+- Settings persistence with SharedPreferences
+- Graceful error handling for GPS/permissions
+- Responsive design principles
