I've used another automated tracking app before and this one is so much better. I can see the times where I was actually using work software and files vs when I've left my desk to take a call or attend to a personal matter. With one click I can allocate a billable task to the tracked time or the space between.
Excellent time tracker, project management app, invoicing, expense tracker and so many other features. I have been using it for years and it has literally saved hours of my time in things i'd rather not have to do manually. Bonus feature, full Linux support!!!!
