 # GPS Speedometer

-A customizable Flutter speedometer app using GPS location services to display real-time speed.  
+A GPS Speedometer aimed at Android on Motorcycle / Bicycle applications.
 **Created with the help of Claude Code**

 ## Features

 ### Core Functionality
 - Real-time speed display using GPS
- High-precision location tracking
- Works offline (no internet connection required)
- Automatic portrait/landscape orientation support
+- Maybe also direction display using GPS
+- Good floating window / split screen support(hopefully)

 ### Customizable Settings
 - **Speed Units**: mph, km/h, knots (with convenient unit selector buttons)
- **Display Style**: Digital speedometer, analog gauge (tap gauge to switch)
 - **Theme**: Light/Dark mode (expandable for custom themes)
- **Metrics Display**: Toggle additional metrics on/off
-  - Current location coordinates
-  - Distance traveled
-  - Trip duration
-  - Current speed accuracy

 ### Technical Specifications
 - Target Platform: Android (primary)
- Screen Orientation: Auto-rotate (portrait/landscape)
 - Target Device: Mobile phones and tablets
 - GPS Requirements: Location permissions required
 - Offline Capability: Full functionality without internet

-### New Features in v1.1
- **Auto-rotate Support**: App now supports both portrait and landscape orientations
- **Interactive Gauge**: Tap the speedometer to switch between digital and analog modes
- **Extended Units**: Added knots as a speed unit option
- **Unit Selector**: Quick access unit selection buttons next to the speedometer
-
 ## Architecture Design

-The app is designed with customization and extensibility in mind:
- Settings system supports multiple options per category
- Modular design allows easy addition of new speedometer styles
- Theme system supports unlimited themes
- Metrics system allows toggle individual data points
+*To be updated*

 ## Permissions Required
 - `ACCESS_FINE_LOCATION` - For high-precision GPS tracking
