I couldn't help but try this.

Great find! I was actually looking for a similar iOS app recently but couldn't really find a good one. I've felt lately like I don't do a lot of math these days and that I might be slipping.
After maxing 30 for about 5 minutes I got a bit bored though. I think the countdown could be a bit faster. Guess I'll have to set it max 10
Of course, once I turned on the square I was done :D
Great app - I would love to know what others got! I got a 405 :)
