From the developer:
ArcGIS is a great way to discover and use maps. Maps come to life in ArcGIS . Tap on the map or use your current location and discover information about what you see. You can query the map, search and find interesting information, measure distances and areas of interest and share maps with others.
Find community hosted maps from ArcGIS Online - ESRI's online GIS. Alternatively you can use the authoring tools on ArcGIS .
