I have looked around the web, and although there is some information about CANDE, no other data could be found for the information tags. The official website is also not working at the moment, which makes it impossible to contact the developer of the application.
Since the only way to solve this is to get in touch with them, try at a later time, because the website might be in maintenance: (not working at the moment) http://www.candeforculverts.com
