Food delivery apps are mobile applications that allow users to order meals from local restaurants and have them delivered to their homes or workplaces. Users can browse menus, select items, and pay through the app, making the process convenient and quick. Popular examples of these apps include Uber Eats, DoorDash, and Grubhub. These apps often provide features like real-time tracking of deliveries, user reviews, and special promotions. They have become increasingly popular, especially during times when dining out is less feasible, offering a wide variety of cuisines and options to suit different tastes and dietary needs.
