What do you like best?
Toggl has been beyond helpful to me as a freelancer. It allows me to jump from project to project, take breaks, and pick back up in any project where I left off, all while keeping an accurate, well-organized record of what I have done, when, and for how long. It takes so much stress out of time-tracking and record keeping.
What do you dislike?
At times, it does seem to be a little buggy. (For instance, lately, when I start up Toggl again after having not used it for several hours, it will tell me I am hours and hours into a project I haven't touched in weeks/months. I simply stop the timer and delete the entry, but it is a bit annoying to have to deal with.)
