Simply the best graphing on iOS

I dont usually review apps and I feel a little guilt as I know how important the feedback loop can be to development. I just wanted to tell you I own just about everything (literally) Math and Geometry related in the App Store as I do a little theoretical physics and I have been collecting the best of the best for teaching my son just about everything. You can not go wrong with this, if you like it please give the author feedback so he keeps improving (last update was very nice).

Just a tiny feedback: The only environment I use that has features this doesnt have in on OS X (Windows has a nice one too) but in OS X you can plot functions along time and space which is really nice and they have just a few other extra features that I would be happy to even pay for should you get them in. Seriously, you have the best graphing environment, it looks great, if you had time you could do fractals on this.
