Well, as we said, fitness trackers contain the altitude sensors too. The altimeter sensor helps to track the altitude of your legs while climbing the stairs and hence the tracker knows you are climbing stairs.

Also, when you take a step on a stair, the air pressure changes. It is also sensed by a sensor. Together, these two sensed measurements conclude in your flight of stairs that you are taking.

Hence, your tracker is able to differentiate when you are simply walking or taking stairs. It can even track the number of stairs you climbed. Some fitness trackers come with a built-in GPS and altimeter and some use the phone’s GPS.
