An app, short for "application," is a type of software that can be installed and run on a computer, tablet, smartphone, or other mobile or desktop device. Apps are designed to perform specific functions directly for the user or, in some cases, for another. They are self-contained software packages that allow users to perform specific tasks. Apps were originally intended for productivity assistance such as email, calendar, and contact databases, but the public demand for apps caused rapid expansion into other areas such as mobile games, factory automation, GPS and location-based services, order-tracking, and ticket purchases, so that there are now millions of apps available. Many apps require internet access and are generally downloaded from app stores, which are a type of digital distribution platform.

There are different types of apps, including:

• Native apps: These are apps that are developed for a specific platform, such as iOS or Android, and are installed directly onto the device.
• Web apps: These are apps that are accessed through a web browser and do not need to be installed on the device.
• Hybrid apps: These are apps that combine elements of both native and web apps.

Apps have gained popularity as they are beneficial to company owners and large organizations. Some of the vital benefits include assisting business owners in rapidly deploying software that improves the company’s efficiency, being less expensive than other types of software, and boosting a company’s productivity.
