Space Timer -- Coming soon to the Mac app store!
Space Timer was designed to help keep track of time for those that work on multiple projects at once and need to know how long they have been working on each project.
If you work with spaces to organize your work flow and need to keep track of how much time you spend on each project or space--Space Timer will help you do just that! Space Timer is a small utility application that keeps track of how long you have been using a space with an application open. Start Space Timer before you open an application in a space and it will automatically keep track of how long you have been using that space with that application active. If you want to stop timing spaces simply close or hide the application you are using or move to an empty space.
