Rangeland inventory and monitoring have been transformed during the past 10 years by a number of major innovations. This paper reviews the status of two new mobile apps (LandInfo and LandCover) that are part of a larger “Land-Potential Knowledge System” (LandPKS) that is being developed to capitalize on these four innovations in order to provide the knowledge and information needed to make land use and land management decisions at individual field, pasture, or ecological site scales. It focuses specifically on the opportunities to use these apps to support inventory and monitoring by landowners and land managers. The apps can be used to collect data that is compatible,and in many cases entirely consistent with the BLM's Assessment, Inventory and Monitoring,  and the NRCS's National Resources Inventory program. Other featuresinclude one-time data entry and permanent cloud storage on a web portal and data visualization tools.
