Usability Evaluation on Mobile Devices, Practical Case

Usability is an attribute of software quality that needs special attention in app development. In the present document, we analyze aspects like visual clarity and error prevention in a massive consumer app for passenger transport. With the purpose of knowing the influence of these aspects in the success or failure of an app we submit a survey to 3 developers and 40 users inquiring about these aspects. The results reflect the vitality of the usability principles by both users and developers. We hope the obtained results will help future developers, researchers and/or students.
