The recent proliferation of smartphones has greatly increased the demands of companies for mobile application and mobile web development. In general, a mobile application is divided into a mobile platform-based native application and a web browser-based web application.

A native application is an application that is produced based on a native application programming interface (API) provided by a device operating system and installed directly on the device operating system. Native applications run optimized for the device platform with their compilations complete.

Since the native application is device dependent, the user may access various types of application stores installed in the terminal and search for an application by inputting a search word of an application to be searched in the application store. For example, when a user wants to search for a location guide application, the user may access various types of application stores installed in the device, and search for an application by inputting "location" or application name as a keyword in the connected application store.

Web applications are based on the web standard technologies Hyper Text Markup Language (HTML), Cascading Style Sheets (CSS), and JavaScript (JavaScript). Safari, Opera, Internet Explorer, and IE Mobile A web-based application that runs through a mobile web browser, such as a browser.

In such a web application, all application resources reside on an external web server. Accordingly, when the terminal executes the web application, the application stored in the web server is called through the Uniform Resource Locator (URL) of the mobile web browser. Thereafter, the terminal may receive a web page from a web server through HTTP (Hypertext Transfer Protocol).

Therefore, the web application is built on the web standard technologies HTML, CSS, JavaScript, so there is an advantage that the mobile web browser runs on any device that exists.

However, when a user wants to search such a web application, the user has to access it through a web browser. In addition, since the web application is called through the URL of the mobile web browser, there is a problem that if the user enters the application name as a keyword for searching the web application, the application cannot be called.
