The best flash card program out there (at least for Japanese)

I have learned an amazing amount of words in 3 months thanks to this Application. That alone warrants its costs. The words come up perfectly in sequence just as I am about to forget them. Even if I have forgotten them I soon remeber them again. I am amazed at the speed of this system. I only wish my Iphone and this were available when I started 6 years ago. I only wish I could edit the cards myself. Please come up with a application for your own designed flash cards.
