Magican Rest is a health-care app, which can rescue people from overworking. It's such a useful tool for you to manage your time. For longtime focusing on work in front of your Mac, you may forget the time and forget to rest. Then you can use Magican Rest to preset the break time range before working. When it works, it will cover your screen with a countdown, and then you can do nothing but leave it as it is, using the time to rest your eyes, to go around, to be with your family or just nap. And don't worry, everything you did will be remains the same once the resting time is over.

Requirements:
OS X 10.6
