I have been using Toggl for time tracking, and I love it. So far, I’ve only used it for tracking billable hours, when I’m actually editing. After watching the video in the lesson, I’m excited to try to track more things with it (e.g., admin time, professional development time, etc.). But I’m also intrigued by bjdavis878’s suggestion above of Lifeline. I haven’t heard of it, and I often do forget to turn Toggl on and off (I was surprised to learn this morning that I had a 21-hour editing session logged yesterday – whoops.)
