ArcGIS for iOS extends the reach of your GIS from the office to the mobile Web. It includes an application for Apple iPhone, iPod Touch, and iPad devices that you can download from the iTunes App Store for free and explore maps that are hosted on ArcGIS.com or your corporate ArcGIS Server. Using the ArcGIS API for iOS, you can develop focused applications for iOS devices that can be deployed within your enterprise or to the public via the Apple App Store.
