Unless your devices are rooted, there is not going to be any easy way to do that (you will not have access to the required directories). You could upload your cards to one of the online flashcard sites, but that would not be a perfect solution since it would not copy your settings, and each site has some limitations as to what you can upload. Why don't you contact me at
support@gabysoft.com and I will see if I can come up with another solution.
