GasSaver is a mobile app built with React Native and Expo that helps drivers track fuel efficiency, monitor trip history, and save money on gas. Users can manually input trip data or integrate with OBD-II devices (in future updates) to automate tracking.
MPG Calculation: Track fuel efficiency per trip using start/end odometer and gallons used.
Trip History: View a list of past trips with calculated MPG.
Trip Deletion: Remove individual trip entries from history.
Local Storage: Saves trip data securely to the device using the file system.
Planned Features:
- OBD-II trip sync
- Route optimization based on fuel usage
- Gas station price comparison (via external APIs)
