The aim of the Greencoin mobile application is to encourage its users to change their behavior and to act pro-ecologically. The pilot version of the application will operate within the city of Gdańsk. To keep the app’s user base as large as possible, the graphical user interface should be attractive to the broadest possible audience, and the application itself should be easy and fun to use. This work is a continuation of studies on Greencoin mobile application prototype performed by Radziszewski et al. (2021). The Greencoin mobile application mockups, based on early version of the app’s documentation, were designed. To evaluate these mockups, the authors organized a series of workshops for researchers and stakeholders engaged in Greencoin project, during which several UX/UI designing techniques was introduced and used, including (but not limited to): empathy maps, personas, “jobs to be done”, value proposition canvas. Feedback from workshops participants has been carefully analyzed. It was crucial for the Greencoin team to plan future versions of the app, which will have some modifications to the user interface suggested by the mockups evaluators, and even the app functionality will be expanded thanks to the comments submitted during workshops. Little variation in the age of the workshops participants was identified as a limitation of the research performed. Both users under age 25 and elderly users were underrepresented. To answer this issue, an online questionnaire was prepared and sent to potential Greencoin application users of different age groups. As the future users of the application are a diverse age group (from youth to the elderly people) but living in the same city, their preferences may be specific to a given region. In the process of UX/UI design of the mobile application for this kind of user base, their specific preferences needs to be taken into account (Rogoś-Turek B., Mościchowska I., 2015).
