today announced the availability of the first public beta of MacBreakZ 4, the latest release of the break timer for Mac OS X. The company says version 4 is “more than a simple upgrade, but is a re-thought, re-designed and re-written product developed in cooperation with a dedicated group of volunteer private alpha testers. The new version is completely re-implemented using Mac OS X’s native Cocoa libraries, but remains true to the spirit of earlier versions that repetitive injury prevention should be a fun rather than frustrating experience.” In order to promote healthy computing on the Macintosh, the company has slashed prices by over half for the introductory period of the product: a single user license is available for as low as US$9.95.
