Researchers generally have not been able to keep up with the rapid pace of mobile app innovation in many ways. One of those holes is with typology. Not being able to clearly describe mobile app artifacts, as a way to start a discussion about them, is a key factor holding researchers back. This chapter splinters off a promising but relatively underdeveloped genre of mobile apps, the locative ones that juxtapose interactive digital media with particular physical environments, for closer examination and better labeling. This piece quickly provides theoretical, historical, and contextual overviews to help situate locative apps as a genre of importance. It then provides informal frameworks, as thought exercises, for examining and understanding apps through a locative perspective. Two cases, also led by the author, will then be taken through this process to illustrate what can be learned from it, followed by reflections and suggestions for related future areas of inquiry.
