Dmitry Nikolaev & Co (http://getnumi.info) have announced Numi 2 for Mac OS X. It’s an update of the next generation calculator.
Numi combines calculations with text and allows you to share computations with other users. It automatically “understands” and computes what you write. You can type text, or simply paste it in. Numi adds up all the numbers for you, and displays the result. The new version introduces many new features such as modes, variables, new operations, global hotkey, accessible results and more.
Numi 2 is offered at the special launch price of US$4.99 and is available worldwide through the Mac App Store in the Productivity category (http://tinyurl.com/n6w8946). It requires Mac OS X 10.6 or later.
