The DKW charts are compatible with both WinGPS 5 (for Windows) and WinGPS Marine (for Android and iOS). If you have both software packages it is possible to use these charts in both programs without having to buy extra licenses.
Please use
DKW Manager for installation on Windows. For installation on an Android and iOS device you need to log in with your account in the app, and go to the chart manager to download your chart.
