10 Best Back-to-School Apps

Graphing Calculator
Available for: iPhone, iPad, iPod Touch
Price: Free

In the arms race of school calculators, the graphing calculator was always the aircraft carrier to inferior devices' cruisers and tugboats. Hard-core students will still bust out a Nimitz-class scientific calculator every so often, but the Graphing Calculator app provides a higher-powered option to students who want more out of their calculator than the ability to spell out "boobs" by inputting 59009 and turning the device upside down. The Graphing Calculator app includes an expanded scientific calculator, the ability to graph multiple equations and a function that emails the results. This app may not be the big, bold graphic calculator of classrooms past, but last we checked those didn't have iTunes or apps for just about every arcade game ever created, either.
