Publicspace.net today announced the availability of MacBreakZ 4, the latest release of the break timer for Mac OS X. The company says the new version is a re-design based on almost 10 years of experience and feedback from users. It was entirely re-implemented in Mac OS X’s native Cocoa environment. The redesign focused on making it easier than ever to kick bad work habits and make yourself both more productive during work and less tired after work. A lot of effort went into making the program less disruptive and to offer a smoother transition from your current work habits to a healthier work life, notes the company. MacBreakZ 4 carries a launch day special price of US$24.95 ($29.95 regular price).
