Version 2.8 of MacBreakZ – the strain-prevention utility – has been released by publicspace.net.

MacBreakZ 2.8 – which contains a number of bug fixes – helps prevent repetitive strain injury (RSI) by prompting the user to take breaks, based on activity levels. Continuous computer use is believed to be a key cause of RSI in the hands, wrists and fingers.

The break-prompts – in the form of screen messages - also make suggestions exercises to relieve stress and enhance posture.
