There is no one PC app that is supported, but there are several export options you could use.
First, you could export in CSV format, which is a text format many apps can read (eg excel).
You could use study archive format, which is CSV with media files like images. It is just a zip file, so you can unpack it to get the contents.
There are also a few slide export options, such as HTML and jpeg images. These work well for other platforms.
Hope that helps.
