Long gone are the days when students and scientists needed to buy graphing calculators—now they have apps for that. The Quick Graph app is one example (and a good one at that), as it was voted the best graphing calculator available on the iTunes AppStore. The app interface is very simple, as users are merely faced with a digital depiction of graph paper. From there, users can easily graph equations entered with the built-in scientific keyboard by selecting the “+” symbol from the menu bar. In the free version of the app, only equations in the form of “variable = f(variable)” are accepted. The app also includes a small library of built-in example equations to get users started. Graph images can be shared via email or saved to the device’s photo library.
