Power Manager helps you save energy by reducing the running costs of your Macs. The savings appear on your energy bills, and in the time you save by taking advantage of Power Manager's ability to automate back-ups and other repetitive tasks. Power Manager includes everything you need to save energy, time, and money. Power Manager augments Mac OS X's built-in energy saving capabilities. With Power Manager you can create an energy saving schedule that suits your needs. Unlike Mac OS X's Energy Saver, Power Manager can power on and off your Macs whenever you require. Power Manager provides a predictable and customisable sleep after inactivity task. No more wondering why your Mac is not sleeping after being left idle. Power Manager's inactivity task will put your Macs into a low power sleeping state in a predictable, timely, and energy efficient manner.
This allows you to control ON, OFF, launch times & much more. You can customize in so many ways, it's amazing. You can do any day of the week, have it sleep, pause, launch applications. Apple should build this into it's operating system!
Cons
Though very flexible, could use some polishing on it's interface.
