I often find myself compulsively logging in to Google's AdSense to see how much I've made today. Given that it's never more than a dollar, I can't really explain my compulsion, but rather than fight it, I decided to find a tool to automate it. When I went looking, what I found was SysSense. SysSense will sit unobtrusivly in your system tray and poll your AdSense account at regularly configured intervals, and pop up a balloon tip with the details of your earnings. The current version of SysSense can handle multiple accounts, and show data by individual ad unit, or by page. It has just been updated to version 1.2.11 to handle recent changes made by Google to AdSense. SysSense is donationware for Windows.
