DeskTime

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

I've been using this amazing app since 2015 to log my work on my daily tasks as an employee. And also, to analyze my productivity. It also tracks my work arrives and work leave every day. This feature helped me a lot to keep track my working hours weekly.
