The eVSM software is an add-on for Microsoft Visio and runs anywhere the desktop version of Visio is supported.
It can also run on a Mac, provided Windows is installed via Bootcamp or Parallels. Currently, Visio—and by extension eVSM—is not supported on iPads or smartphones. However, eVSM is fully supported on Windows tablet PCs, including the Microsoft Surface Pro.
Note also that eVSM is required to create and edit eVSM maps. These maps can be exported to PDF format, which can then be viewed on any device or platform.
