TestSoup wants to be king of the flash cards:

It’s an online flashcard system with a library of pre-made flashcards for sale. The cards are well put together, and cover things like GMAT, GRE, and the SATs. Best of all, if you want to study on the go, they’ve got iPhone, Android, and Blackberry apps.

TestSoup definitely has one thing going for it: speed. The interface is quick to get around and the cards themselves are very responsive. You can easily flip through a deck as quickly as you can click.

It could certainly use a bit more visual flair, but it’s off to great start. If you’re looking to study for something and they have cards available, it’s definitely worth a shot. Follow them at @TestSoup or check out their blog, which is just getting rolling, but focuses on studying strategies.
