Excellent graphing program – Quick Graph Review

I've been using this program with my students. It's quite simple to use and produces excellent results. I've had a few small problems with it, and the support people are very responsive and helpful. From my correspondence with them I know that they are planning new features soon to make the program even better. While it's hard to compare applications on the iTunes store (store people please take note!), so I haven't made a thorough comparison of the different apps available, this one seems rare in its ability to graph equations that are not defined with y as an explicit function of x (though that does require the very inexpensive add-on feature). It was already a great program, and the latest updates have made it even better. You should get this.
