The Cruiser app can only be used on the operating system (e.g. iOS) it was bought on. A transfer of the app on another plattform (e.g. Android) is technically not possible.
Every app is connected to your user account (Apple ID or Google account). NAVIGON has no access to your user account.
If you want to use the Cruiser app on another operting system, please purchase it again from the new app provider.
