Our Review:

SpeedCrunch is the best scientific calculator. I like the lists of constants, functions and variables available along with the math book.

The math book gives useful information such as how to get the volume of a cube. Other cool features are customizable result format, angle format, behavior and radix character. The features are a little complicated for someone wanting to perform simple math.

The current version 0.11 removes the small buttons appeared in the previous version 0.10.1 and now you have to rely on the physical keys on your keyboard to enter numbers.

The program is available across multiple platforms including Windows, Mac OS X and Linux. The Debian package for Linux at the Ubuntu Apps Directory is an old version 0.10.1 at time of writing.
