I teach math for a living. This is perfect for quick visualizations and analysis. My son/daughter are compelled by their school to buy pricey "graphing calculators"...QuickGraph is faster and easier to use by far...and it is on their iPhone, so they dont have to carry around a one trick pony paperweight.

I keep finding new uses for this thing. 5 stars.
