Publicspace.net has released Vitamin-R 1.64 (http://www.publicspace.net/Vitamin-R/index.html), an update of its Mac OS X compatible productivity tool for creative professionals. The new version adds support for the Growl notification framework.

Vitamin-R is a collection of tools and techniques for managing attention and maintaining motivation. According to the folks at publicspace.net, it complements the task capturing and organizing features of modern to-do list managers by forcing you to concentrate fully on one task a time and keeping distractions at bay. It breaks down large, vaguely defined tasks into a series of short “time slices” of between 10 and 30 minutes, each with specific and actionable objectives.

Vitamin-R provides you with the “Now & Later Board,” complete with FastType magic, to give you a place to quickly dump all those things that go through your head and allows to get back to the task at hand. It requires Mac OS X 10.6 or higher.

The single user version of Vitamin-R is available for US$19.99 from the Mac App Store and for $19.95 from the publicspace web store. The web store also offers family, business and enterprise licensing, and customers may chose to include a “forever upgrade” with their purchase. Each Vitamin-R web store purchase includes a free license for its companion product, Noise Machine, which is also available separately starting at $4.95.
