rooSwitch Lite offers multiple profiles for most of Mac OS X’s iApps including Address Book, iTunes, iPhoto, Mail.app, Safari and Stickies.

As the developer Brian Cooke explains:

rooSwitch makes it easy to keep your favorite apps data safe and also makes it easy to manage profiles for different situations. A good example of this is are “at home” and “at work” profiles.

rooSwitch Lite is the freeware, restricted version of rooSwitch (shareware, USD 14.95). It doesn’t have the range of apps that the shareware version offers or the Automator and AppleScript support, but it does offer unlimited profiles and fast switching between them.

In addition to keeping home and work settings separate, rooSwtich’s profiles are great for beta-testers and developers who need to work with multiple preference and application support files.

Brian has made a movie which demonstrates the app in action and another movie of the shareware version gives additional tips on how to use the app to maximum advantage.
