I could've sworn we've blogged this, but a peek at our extensive archives turned up nothing: App Update, like Widget Update
, is a widget that acts like Software Update for all your non-Apple apps. It allows you to specify any extra directories where you store your apps if, like me, you put them wherever you want
, and it can ping Apple, MacUpdate and VersionTracker to see if any updates are available. App Update even has limited support for checking on Quicktime Components, Frameworks and Preference Panes, and it can be automated, with Growl support rounding off the list.
App Update is free, really handy and available from DashboardWidgets
