Math visualization is vital for students to transform abstract math concepts and to explore math topics. Traditionally math teachers have been using hand-held graphing calculators to help with this type of activities. However, powerful mobile device apps seems to make everything possible. Here we will review several iphone/ipad/android apps that can perform functions that traditional graphing calculators, such as TI-nspire can do, or getting close to them:

## Free Graphing Calculator

Typing the keywords of “graphing calculator” in the iPad app store, you will see the first result is **Free Graphing Calculator** by William Jockusch (as of July 24, 2013):

This app provides a very similar function to some of current hand-held graphing calculators, as shown below. You can tell that this app can do: general calculation, geometry graphing, tables and several shape solvers. It also have in-app references on a number of mathematics topics, such as Algebra, Calculus, Fractions, etc.

**Quick Graph**

Another free iPad/iPhone app is “Quick Graph“. It provides similar functions although no in-app curriculum related contents.

However, it does have one extra function of 3-D graphing. It is also very easy to save all 2-D, 3-D graphing into jpeg format images for future references.
