My startup http://brainracer.com http://brainracer.com is very early-stage, but we're tackling the difficult problem of keeping young kids interested in math. The math education system (especially in the US) tends to be soul-crushing, and it focuses more on repetition rather than intuition. Our first app is guilty of being a little bit repetitive also, but it uses social game mechanics and spaced repetition to make learning arithmetic as painless as possible. Hopefully, it will validate the idea of social math games and create some cashflow. I'm already looking forwarding to the next game we'll build on the iPad -- because of the touch UI, I think it's a perfect medium for exploratory learning.
