The method proposed in this paper, the FitFlip mobile application, was devised as a solution to the problem that originates from online clothing websites like Grailed, whilst providing a useful marketplace to buy and sell, also heavily taxing the users both monetarily and in the user experience [2]. This issue became prominent as it would take up to 30% of the income users would get from selling clothes, despite only acting as a middleman. The FitFlip application intends to solve this problem as it is a community based, zero-fee platform where the transaction terms are stipulated strictly by the users and is not imposed upon by the FitFlip service in any way. This fixes the major issue prominent with services such as Grailed or Depop. Additionally, the FitFlip application seeks to resolve a few other issues prevalent within these popular services, such as inefficient search and filtering tools and the inability to create custom transactions where users can trade items instead of only selling. Within this paper, multiple experiments are performed that ensure FitFlip mobile application has a reliable and consistent user experience [1]. These experiments consisted of an experiment to ensure the response time was efficient, as well as another experiment to determine the consistency of response time given the quantity of data to be loaded. Ultimately, the FitFlip application is more than sufficient solution to the proposed problem, as it provides users with an efficient platform to connect and trade clothing items, which boosts a sense of community and encourages the reuse of clothes.
