"Excellent and very useful." [IR MANSON from US, Apr 28, 2015]
"Ezygraphs can handle all the 2D functions I'll ever need to graph. There is no delay from entering the function to graphing it. It allows for multiple functions. I can find coordinates of points. There's even an option to view recent functions. Possibly the greatest mobile graphing app there is." [hansenjiang from Canada, Aug 27, 2015]
