Abstract: With the dramatic growth in the mobile market and has reach a range where some software development company cannot neglect the need to contribute in it any longer. Designing a native mobile application involves lots of resources and this, might affect some of the issues with applications development and deployment. At present, there are different mobile device manufacturers which have different devices and development tools. The main solution to solve this issue would be to design a cross-platform application which exist on all mobile operating systems (OS), as it operates in some browser and consequently, can reach the major possible number of end-users. User-centered design (UCD) is a framework of processes (not restricted to interfaces or technologies) in which the needs, wants, and limitations of end users of a product, service or process are given extensive attention at each stage of the design process. In this paper, we propose User-centered design (UCD) for platform independent applications development is smartphones with different operations system.
