A web-based application is any application that uses a
web browser as a client.
A Web application (Web app) is an application program that is stored on a remote server and delivered over the Internet through a browser interface.
Within the mobile computing sector, Web apps are sometimes contrasted with native apps, which are applications that are developed specifically for a particular platform or device and installed on that device. However, the two are not mutually exclusive because many applications contain elements of both native and Web apps.
