This app fills a much-needed void by keeping my Mac "caffeinated" when I have apps running that have yet to be updated for Mountain Lion. My sole beef with this app is the interface. That dial is, quite seriously, incredibly lame. It'd be a fine idea for a touchscreen interface, but on my Mac I have to repeatedly "spin" the dial with multiple and rather awkward combinations of mouse clicks/movements. This really needs to be thought out differently.
