Downloading Wolfram Alpha 2.1.4 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The program lies within Education Tools, more precisely Reference. This software for Mac OS X was originally created by Wolfram Alpha LLC. We recommend checking the downloaded files with any free antivirus.
From the developer:
Building on 25 years of development led by Stephen Wolfram, Wolfram|Alpha has rapidly become the world's definitive source for instant expert knowledge and computation. Parts of Wolfram|Alpha are used in the Apple Siri Assistant; this app gives you access to the full power of the Wolfram|Alpha computational knowledge engine.
You may want to check out more software for Mac, such as MenuApp for WolframAlpha, Wolfram CDF Player or PNG32 - Alpha Channel PNGs - Made easy!, which might be similar to Wolfram Alpha.
