The user can measure distances on the map. To do this, turn on the ruler mark in the lower right corner of the map (after turning on, the mark will turn green). By clicking on the desired locations on the map, the app shows the distance between them (a red line appears between the points and the distance between the points is shown in a red area above them).
To end / cancel the measuring function, press the ruler mark again (after switching off, the mark turns white).
