"Awareness" is a handy PC application that helps its users be more aware of the time they spend on the computer.
Developed by Futureproof, the utility can be configured to remind computer users to take a break away from their workstations at specific times; thereby lessen physical conditions and afflictions that're associated with long term computer use.
Available in versions for Mac OS X (10.6 or later) and Windows (Windows XP or later), the utility is non-intrusive with the way it issues reminders - making it a handy application for PC owners to have.
