If you use this for academic publication, I would appreciate if you could cite this application in your paper/book.
For example, if you download version 2.1.0 in 2018, the citation in APA format looks like this:

Here's a slideshow which introduces new features (in Japanese, but you can probably get a basic idea of what are possible with this new version).

For pre-Mavericks Macs, try the following older versions. This version does not have R integration and some features are very limited.
The current beta version is 1.9.8 beta (2015/05/09).
The current beta version is 1.9.7 beta (2014/12/05).
System Requirements: 64-bit Mac (Core 2 Duo or later) with Snow Leopard (10.6) or later NOT ON 10.5 Leopard
NOTE: CasualConc beta is compatible with Mountain Lion (10.8), but it is not signed, so you need to two-finger click (or right-click) the application and select Open from the context menu for the first launch. See this page on Apple site for more information.
You can find information about the beta version on this page.
I would appreciate any feedback on functionality/accuracy/bugs/etc. I will try to implement useful functions and improve usability as well as to fix bugs as much as my time and, more importantly, scripting skills allow. Please send any feedback to casualconc (at) gmail.com.
