*** Workstation-class scientific computing for iOS! ***

If you use REDUCE, you can now perform your computations anywhere on your iOS device of choice. iCAS is a complete and native implementation of REDUCE with all of its major packages, including the gnuplot package. If you have an iPhone 4/iPad or later device, you can even use the iCAS screen mirroring feature to share your results/plots with your colleagues, walk a class through computations, etc.

If you're not familiar with REDUCE, it is an extremely powerful and flexible computer algebra system with a track record spanning over 40 years of use in the engineering, computer science, and physics research community. Simply put, iCAS is like having Mathematica or the computational engine of Wolfram Alpha in your pocket but, best of all, it runs natively on your iOS device so no internet connection is required. iCAS is fully programmable and provides the ability to reuse previous results in computations.

iCAS is all about getting computations done. Its simple, clean, and uncluttered interface is quick and nimble and stays out of your way and fancy graphics are used only where it matters, for fancy output and plots.
