The effect of applying the principles and considerations of smartphone applications interface design to improve user experience

Smartphone applications have become one of the indispensable interactive media for any governmental or private institution to communicate with targeted customers, as they play an essential role in our lives because of the services they provide that facilitate many things for us; two factors affect the effectiveness of the application: user interface UI. and User experience UX, which is the feelings of the user resulting from the experience of using it and interacting with the application, whether with satisfaction or dissatisfaction.

The research problem lies in trying to answer the following questions:

Are some applications in Egypt that must be redesigned to improve the user experience?

Does the non-application of the principles and foundations of designing the interface of smartphone applications affect the quality of service or the marketing of the product provided by the application?

What considerations should be considered when designing applications?

The importance of the research is due to the applications' role in supporting the service and investment activities that are increasing in numbers in the application store, and this increase coincides with the development of phone technology and the continuous updating of programs with the emergence of new professional tools for designing user interfaces. It is assumed that the design of application interfaces coincides with these Updates and features to enhance the user experience and meet his needs, which motivates customers to use the service or product and interact with it.

The research aims to Study the foundations and principles of application interface design to reach high-quality applications that address the customer and fulfill his needs.

Highlighting the considerations of interface design and user experience to produce successful applications that are well-designed and attractive to the public.

The research adopted the descriptive approach to collect data for a group of applications in the application store, study them, classify them, and analyze the data to reach the search results. The limits of research are limited to applications in Egypt and Saudi Arabia.

The researcher conducted a survey study that included many applications on the Apple App Store to study the extent to which the principles of interactive graphic design are applied to the user interface. The research results concluded that the survey showed a lack of knowledge of the basics and principles of application design among some of those in charge of producing applications. Therefore, it needs improvement and redesign.
