Take Your Heaviest-Duty Calculation With You Wherever You Go.

RedCrab is a calculator that can be used to make and run sheets of mathematical data, and that can be used portably, on many different devices. On the other hand, this portability means it doesn’t hook as well into a computer or other device as other calculation options like Microsoft Excel can, and RedCrab requires a bit of effort to learn about its unique features. Still, as options for mathematical calculation and presentation go, RedCrab is certainly a good one.
