Food delivery apps are mobile applications that allow users to order meals from local restaurants and have them delivered to their homes. These apps typically feature a user-friendly interface where customers can browse menus, select items, and pay online. Popular examples include Uber Eats, DoorDash, and Grubhub. Once an order is placed, the app connects the customer with a delivery driver who picks up the food and brings it to the specified address. Food delivery apps often provide real-time tracking, allowing users to see the status of their order. They have become increasingly popular due to their convenience and variety of dining options.
