Mobile App Design is a process of creating the visual and associated elements of apps for smartphones and tablets. It focuses on making apps simple, attractive, and user-friendly. A good design is based on good navigation, visual layouts, and easy-to-use buttons so that it would be easy for a user to explore the app easily. A great experience is necessary to provide for all kinds of apps so that users easily explore browsing, doing shopping, or playing games. A well-designed app also adjusts to different screen sizes to make it possible to work perfectly on any device. By combining creativity with functionality, mobile app design helps build apps that people can enjoy using.
