This paper presents a user-centered mobile solution to evaluate the performance and success of the service's infrastructure at the level of Urban Mobility, Tourism, Airports (Air Transport), Stadium (Arenas) and security in mega events. This infrastructure is noted from the perspective of legacies and its impact is evaluated through a collaborative process between the KPI, as a tool installed on each mobile device, and the end user. This project is financed by the National Council for Scientific and Technological Development (CNPq) and aims to identify the relation between the values of investments applied to 2014 FIFA World CUP and the dimension of the resulting legacies.
