Studybuddy doesn't allow you to import your cards from flashcardmachine. I have yet to find a compatible app or a way around it (like exporting them for iPod and then putting on another application).
Update: Using AnyMemo. It works. Open Flashcardmachine.com on phone, export a list (saves on your phone), then install anymemo and import it as a tab-text (under settings).
Hope this helps people in the future.
