Timing 2 is a productivity app that tracks and graphs what you do on your computer. It provides comprehensive information on how much time you spend in any other given app, how much time you spend on your computer being productive versus how much time you don't, and so forth. It provides multiple ways to render and view this information, and you can tweak its settings to track different things. It doesn't do much beyond telling you where you spend your time, though new features are occasionally added. It's no productivity suite, but it is useful.
