The focus is on developing an intuitive Graphical User Interface (GUI or UI): the intuitiveness of the app depends heavily on the positioning of the content, its size and layout. Adaptation to the size, resolution of the screen is done. If necessary, UI kits provided by Apple are used, although individual solutions are used by default. Suitable style elements such as typography and color selection are also defined.
An intuitive design for an optimal user experience (UX). The iOS app experience should be clear, organized, and understandable at a glance. A clean user interface makes apps more harmonious. Functionalities should be integrated in such a way that they are clear, precise and to the point. The goal is to cover the entire functional spectrum of the iOS native app with as few clicks as possible. The size, arrangement and design of the buttons play a central role. There are several design programs to achieve the final design of an iOS application: Adobe XD, Figma, InVision, etc. After that comes the phase of mobile application development.
