This altimeter works exclusively with the air pressure sensor of your smartwatch and thus brings the functionality that earlier mountain watches had.

This also means that you have to adjust the height in the app settings if you are at a fixed point from which the height is specified.
-> This is how you get an exact height information

In addition, the air pressure is displayed at 0, if it is above 1013 hPa, the weather will be better, otherwise it will be worse and you should rather shorten your tour.

Since the altitude is determined exclusively via the air pressure and not with the help of GPS, the app is particularly energy-saving and thus protects your battery. In addition, the height measurement switches off automatically when not in use, so that the battery life is sufficient for even the longest trips.
