Description from the publisher
TimeBreak is a simple utility that can monitor your kids' time spent on the computer, and automatically log them off or lock their session when their assigned time is up. You can configure how much time is available for each kid each day of the week, and also specify allowed time ranges (e.g. no computer use before 6:00 pm). Additionally, you can specify bonus rules, letting your kids earn bonus time for fulfilling various tasks (like chores).
