Numi

Here's how it works. Type text, or simply paste it in. For example, you could type something like this:

50 apps * $1.99 each + 3 apps * $4.99 + Photoshop for $600

Numi gracefully adds up all the numbers for you, and displays the result on the right-hand side. Of course, it can handle more complex math than the simple example above. Either way, you don't have to rewrite what you enter - whether it is text, numbers, or comments - Numi automatically understands and computes what you write.

All features:

* All Text features: Add comments, or titles right inside your calculations. Numi comes packed with all the benefits of a text editor: copy, paste, undo, and fast navigation.

* Autosave: You don't lose your calculations upon exit. All your calculations are automatically saved after exit, and will be loaded when you relaunch.

* Auto-format: The program automatically formats the text, calculations and results, thus ensuring better display and readability.

* Totals: Automatic calculation of the totals for all the results is recalculated automatically. In order to get a grand total, it's as simple as writing "Total".

* Optimized for retina displays.

* Global Shortcut: Being able to quick launch app with global shortcut saves you time and makes all your calculations within reach.

* Accessible results: All your results are available for copying with just one click over them. When you copy text from Numi to another application, the results will be copied, as well.

* Two modes: You can choose between dock mode or menu-bar mode.

* Configurable precision: Numi uses the maximum available accuracy during calculations. You can configure the number of decimal places to display.

* New functions: The application supports a full set of arithmetic and trigonometric functions. Special operations for better handling percentage are a big plus.

* Variables: Automate your calculation workflow. Use variables for automatic recalculations.
