1. A computer-implemented method, comprising: accessing, by a computing system, information that identifies, as a result of requests by a particular application program on multiple computing devices, a first level of either battery consumption or wireless data transfer by the multiple computing devices; analyzing, by the computing system, the accessed information to determine one or more values that identify, as a result of at least a subset of the requests by at least a subset of the multiple computing devices, a second level of either battery consumption or wireless data transfer by the at least a subset of the multiple computing devices; and providing, by the computing system and for display by a particular computing device in cooperation with a display of a network-accessible application program software marketplace, an indicium that indicates the one or more values, wherein the application program software marketplace provides application program software for execution by the particular computing device and other computing devices that access the application program software marketplace.
