iPhone "Algebra Helper 1" experience

I am currently working on multiple iPhone applications which I will be releasing very soon to the Apple AppStore. I have released one application so far, and the results so far is very encouraging. I am going to mainly focus on Education, as I see a potentail needs in the near future on the iPhone and iPod Touch devices.
