Obviously, Fitbit is an activity tracker, there isn’t any doubt about that but there are some nice features with Fitbit’s line (along with others) of activity trackers that have been extremely useful in the DevOps and Infrastructure area of my current job. I have the Fitbit Charge 2 and for an activity tracker it does everything I would want and it is perfect for what I need, even though I’m not as active as I want to be.
