Car Coop is the mobile companion app for the self-hosted Car Coop platform. Use it to manage everyday tasks inside a private car-sharing group: - book vehicles with calendar and list views - record trips, mileage, and shared costs - track expenses and payments between members - post updates on the group message board - save the current parking position and navigate back to the car - choose the server URL of your own Car Coop instance The app is designed for groups that want a practical mobile client without depending on a centralized service.
