We aren’t developing an app for Windows Phone ourselves, but our partner „vsappware“ has launched „GeoMeterPro”. This app uses Outdooractive maps which can be purchased in the app. If you have any questions or concerns do not hesitate to contact the developers of the „GeoMeterPro“ app.
You can find further information about this app on the official website of „vsappware“.
You can purchase the app in the Windows Phone Store.
