It provides drivers with tools to receive and manage orders, set delivery locations, and update order statuses. For restaurants, it offers tools to manage the menu, receive orders, and track dispatched orders. Customers can place orders, track their status, and communicate with both the driver and the restaurant. The app enhances user experience with easy-to-use interfaces and real-time updates to ensure fast and efficient delivery.
