Usability and UX (User eXperience) are some of the most important factors for evaluating the quality of mobile applications.They focus on how easy to use an application is and the emotions that such use evokes.However, these aspects are often evaluated separately in industry through different evaluation techniques.Although it is possible to identify more usability and UX problems by employing different UX and usability evaluation methods, this distributed approach may not be cost effective and may not allow to thoroughly explore the identified issues.In order to support the identification of both UX and usability problems in a single evaluation, we have proposed Userbility, an UX and usability inspection technique that allows evaluating these aspects in mobile applications.This paper presents an empirical study over the second version of Userbility to verify its feasibility.In this study, we compared Userbility with the UX and Usability Guidelines Approach (UUGA) that helps the evaluation of usability and UX separately in mobile applications.According to the quantitative results, considering efficiency, UUGA was better than the Userbility technique.However, the qualitative results suggest that Userbility pointed more improvement suggestions, which could be useful for redesigning the evaluated application.
