This app is Free for teams of two. I find that viewing reports categorized by active boards, co-workers as well as the amount of hours spent on a task are much easier.

I like that you are able to keep track of the time spent on a project. Which comes in handy when you need to bill a client for the time spent or to keep track of an employee to see what needs adjusting to their schedule. Control whether or not they have too much on their production list or if you need to add more to it. You can add the power up to the board directly so it isn't on the ones that you don't need it for. You are able to create a report from it. It is very user-friendly.

Time tracker is great for teams and allowing yourself to see how much time is spent on one project and card, and pull reports and analytics in relation to such.
