Fitness trackers aren’t that complicated: they count your steps, measure your pulse rate and record how long you’ve spent exercising. If they’re sports watches or smartwatches with GPS aboard they can also track your location.

Usually the devices come with the possibility – or the requirement – to connect them to a smartphone or a computer. The collected data is then transferred, saved, and evaluated.
