There are no immediate plans to bring WriteMapper to Linux or Android.
As of now, WriteMapper 3 is only available on macOS and Windows as a desktop app, and WriteMapper 2 on macOS, Windows, iPadOS and iOS.
None of this is set in stone, however, and we will continue to examine our plans moving forward by looking at our users wants and needs. Should there be sufficient demand for support on any additional platforms, we'll be happy to move forward in adding it to our product lineup.
