SoarPilot can act as a flight logger when connected to a GPS. These logged flights can be exported to so called IGC files for later analysis using programs like SeeYou or CouTraCi (see Links page) or uploading to the Online Contest (OLC) server.
Because of the requirements, SoarPilot is not an approved IGC logger and it’s not likely it will ever become one, see this FAQ, however SoarPilot is since 2006 on the list of "Approved Software" of the OLC.
