"Blue Lightning Labs today announced a sale on their popular iPhone application Mathemagics, an application for learning to mentally calculate math problems at phenomenal speeds. For a limited time Mathemagics is on sale at more than 60% off."
I bought this for the kids, to help them with their math memorization, but I find myself playing with it ocassionally just to test myself. And at $0.99 USD, the price is right.
