What Is Mobile Application Design?

Before discussing methodologies and best practices, it is important to understand what is app design and why it matters.

Mobile application design refers to the process of planning, creating, testing, and refining the user experience and visual interface of a mobile application. It encompasses everything users see, touch, and interact with while using the app.

It should not be just an aesthetically pleasing screen. It must allow users to do their tasks in as short time possible, move around freely, and make them understand the way the application works easily.

It has often been wrongly considered that design consists of nothing else but colors and icons. Design actually covers aspects such as usability, navigation, information structure, interaction, etc.

It is also important to distinguish design from development. While mobile app development focuses on building the application’s technical functionality and infrastructure, design focuses on how users interact with those capabilities.

A successful application combines both disciplines to deliver an experience that is useful, reliable, and enjoyable.
