Application Development is the process of designing, coding and building software applications. Application Development is a broad term that covers many different aspects of developing an application.

There are two major types of Application Development: Web Applications and Mobile Applications. Web Applications are designed to be accessed through a web browser and Mobile Apps are designed to be accessed through a mobile device such as a smartphone or tablet.

Web applications can be either native or hybrid. A native web application is built with the programming language relevant for that platform whereas a hybrid web application uses a combination of technologies or frameworks to deliver an app-like experience on the web, such as HTML5, CSS3, JavaScript and other open-source technologies.

Mobile applications are developed using only one programming language (usually Swift for iOS development or Java for Android development) but they can also be hybrid apps too if they use specific frameworks that allow them to run on both operating systems like PhoneGap.
