Thank you for your post. Currently, you can export features in the following formats: KML/KMZ, GPX, CSV, or Shapefile (requires a Pro subscription). The easiest option for importing into ArcMap will be the Shapefile option, but again this requires a Pro subscription. Please note that any commercial/work-related use of the app does require a Pro subscription on each device in use. If you have any questions regarding the subscriptions, please see our website avenzamaps.com, or feel free to contact our Sales team who can help answer any questions.
If you have any other questions regarding export formats, please feel free to let us know.
