How do I create an app interface?

An application interface, or user interface, is the set of features an application provides so that a user may supply input to, and receive output from, the program . If you think about Microsoft Word, as an example, the application interface includes a central area for typing and adding feedback on your screen.

User interface (UI) design is the process designers use to build interfaces in software or computerized devices, focusing on looks or style . Designers aim to create interfaces which users find easy to use and pleasurable. UI design refers to graphical user interfaces and other forms—e.g., voice-controlled interfaces.

A mobile user interface (mobile UI) is the graphical and usually touch-sensitive display on a mobile device, such as a smartphone or tablet, that allows the user to interact with the device’s apps, features, content and functions.
