In this paper, we described the implications that different market and technology trends have on the mobile application development market. The current evolutions show that the game for the developers has changed dramatically. There are many new opportunities for them to develop, distribute, and generate significant revenues with the emerging mobile application portals. Since the mobile application development landscape has substantially changed over the past several
years, mobile development platforms have become more integrated and generally play the role of application portal, device manufacturer or both. As discussed in the paper, application portals tend to become more centralized, facilitating the link between developers and consumers. Moreover, several new platforms entered the open source community to lower their costs and possibly extend their consumer market by lowering prices and as a consequence increase their developer pool. In this changing environment, choosing for which platform to develop reveals to be challenging and we proposed three simple criteria: market size and accessibility, career opportunities, and creative freedom.
