Best App--no complaints--cannot believe how affordable it is

I just want to thank the app creators. This is the best app Ive ever purchased. Period. So affordable. Does everything a graphing calculator does, but I would argue that its better. The graph graphics (pun intended) are kind of stunning -- yeah, stunning. My professor allows me to use it in class on my iPad. Life is good. Love this app.
