Delivery apps are mobile applications that allow users to order food, groceries, or other products from local businesses and have them delivered to their doorstep. These apps connect customers with restaurants, stores, and delivery drivers, making it convenient to access a variety of items without leaving home. Popular examples include Uber Eats, DoorDash, and Instacart. Users typically browse menus or product listings, select items, and pay through the app. Once the order is placed, a delivery driver picks up the items and brings them to the customer's location. Delivery apps have gained popularity due to their convenience and the growing demand for home delivery services.
