DeskTime is a simple and secure time tracking app that lets you increase your company's effectivity and productivity.
Monitor daily activity, sick leaves, vacations and overtime with ease, and get a clear overview of your team's workflow.
I've been using DeskTime for about a year now, and it's helped me to conduct interesting productivity experiments, as well as accentuated that I use social media waay to often.
Pros:Easy to use, visually aesthetic, the Pomodoro timer
Cons:Adding some productivity fact pop ups could be fun
