Tracking time is very easy. I have used this tool for a few months now and I really enjoy the way it is able to handle different projects. Review collected by and hosted on G2.com.
The only thing I can think of as a downside is that I have to be allowed for every single project I want to book time on. As a new worker in my company that takes some time in the beginning, but it should be fine soon. Review collected by and hosted on G2.com.
