Chronos is a time tracking application with a clean and intuitive user interface. It is designed to be minimalist, so you can focus on your work.

Tracked work periods are organized in projects and tasks. Time tracking can be started or stopped from within any application using custom global shortcuts or the menu bar item. Projects can be exported as CSV files.

Features:

• Only time tracking
  Tracking time has never been easier. No invoicing, no clients and no cluttered user interface. You can organize recorded work periods in projects and tasks.
• Projects, tasks and work periods
  Archive old projects and they disappear from the sidebar. Use tasks as todo-list and mark them as done. Flag work periods as invoiced and they won't be added to your total.
• CSV export
  Export single or multiple projects as CSV-file. The CSV format is supported by many apps and can be easily integrated into your workflow.
• Menu bar item and global keyboard shortcuts
  Start and stop time recordings from within any app by using the menu bar item in the upper right corner of your screen or set your own global keyboard shortcut.
• Inactivity detection
  Don't forget to stop tracking your time. If you're not using your computer, Chronos will stop recording automatically.

Chronos requires Mac OS X 10.8 Mountain Lion.
