About Snoop
Running in the System Tray (Windows) / System Status Bar (Mac) you no longer need to endlessly flip between your work and stats. When something happens, Snoop will let you know. Snoop will run on any website or blogging platform that allows JavaScript. Simply insert the tracking snippet on any page you want tracked and we take care of the rest.
