The use of mobile devices has many purposes, including commerce, entertainment and education. Some of these applications deliver information about a city or region. Since these devices are portable and can deliver information where there is internet access, a new potential use is in travels. We call m-traveling. But which free applications are available to aim tourists? What features and problems these applications have? To answer these questions, this work presents three studies cases done in three cities for one tourist, using a total of 20 applications. Analyzing the data collected in the studies cases is possible to highlight some important features and some problems in these applications. © 2012 Infonomics Society. 2631Virrantaus, K., Markkula, J., Garmash, A., Terziyan, Y.V., Developing GIS-Supported Location-Based Services (2001) Proceedings of WGIS'2001 - First International Workshop on Web Geographical Information Systems, Kyoto, Japan, pp. 423-432Steiniger, S., Neun, M., Edwardes, A., Foundations of Location Based Services.
