The Application API is mandatory for Tizen mobile, wearable, and TV profiles, which means that it is supported on all mobile, wearable, and TV devices. All mandatory APIs are supported on the Tizen emulators.
Web Application Models
Tizen provides various application models to allow you to create applications targeted for specific tasks:
The UI application has a graphical user interface. You can create diverse applications with a variety of features, and design versatile applications and intriguing user interfaces with text and graphics while taking advantage of many device functionalities, such as sensors and call operations. In addition, you can, for example, manage content and media files, use network and social services, and provide messaging functionality.
The UI application is the most common Tizen application model.
Watch Application in wearable applications only
The watch application provides a watch face as its user interface, showing the current time and updating it every second. The watch application can be shown on the idle screen of the wearable device.
Widget Application in wearable applications only
The widget application (or widget) is a specialized application that provides the user with a quick view of specific information from the parent application. In addition, the widget allows the user to access certain features without launching the parent application. Combined with the parent application, your widget can have various features to increase the usability of your application.
Web service is a Tizen Web application without a graphical user interface that runs in the background. Web services are useful in performing periodical or continuous activities that doesn’t need user intervention, such as crawling data in the background.
Addon is a type of extension for Web applications. Addon works while the Web applications run. They work commonly on all the Web applications installed and provide some common functionalities, which are not included in Web applications. For example, an addon can show an advertisement before a Web application runs. Addons can be installed and removed separately. However, you cannot run them solely without running the Web applications.
Application Package Manager
The application package manager is one of the core modules of the Tizen application framework, and responsible for installing, uninstalling, and updating packages, and storing their information. Using the package manager, you can also retrieve information related to the packages that are installed on the device.
The application package manager module is expandable to support various types of applications, and designated installation modules can be added to it.

Tizen supports both Web application packages and hybrid application packages, which combine a Web application and one or more native service applications. Applications in the same package follow the same installation life-cycle, handled by the application package manager.
