I downloaded it and had a look.
While I don't think this software would be a very good way to learn Japanese if used alone, and some of the choices of words or their translations in the cards that come with the free version are questionable, the flash card software itself is really quite nice. It's a shame that the deluxe version of the software (which includes more lists and the ability to make your own lists) costs $40, though... that might not be too much to pay.
