Shopping apps are mobile or web-based applications that allow users to shop for products and services online. These apps can be used to browse and purchase items from a variety of retailers, often with the added convenience of being able to shop from anywhere using a mobile device. Shopping apps can also offer features such as personalised recommendations, store locators, and price comparison tools. They can also offer the ability to save items to a wish list or shopping cart, track orders, and view order history. Examples of popular shopping apps include Amazon, Walmart, and Target.
