Better than a TI-Nspire

Ive had this app for a while, but I had to get a normal graphing calculator for AP tests. In terms of the ease with which you can make and analyze a graph, this has TIs top of the line beat by far. The only thing that could make this app better would be calculation of definite integrals.
