I like that Time Doctor can work both online and offline, I don't need a connection all the time and only when I reconnect does it upload all the hours I've worked. Additionally, the interface is really very easy to handle, which makes using it quite simple. I also find the application to be quite user-friendly, as it doesn't feel too intrusive and is easy to use even from the website.

It's a simple tool once you learn how to use it. It also lets you work with other apps at the same time without slowing down your PC.

I like that Time Doctor is easy to use, intuitive, and effective. It was also supremely easy to install.
