Still altitude can be derived from satellite data. All my apps evaluate the unit setting for altitude to distinguish between meter and feet. Now I have to find a specific solution for this device. A little bit strange, isn’t it?
I'm no expert on this but many folks (myself included) use altitude measurements for stair climbing which is (mostly) an indoor activity where GPS's don't work well. I had a vivosport that had this function but it also had a baramoter sensor that was used for altitude both indoors and out.
