Did you know that our iPhone has a built-in pressure gauge? The truth is that it is an elegant way of saying "digital compass", and it is extremely useful when it comes to helping the device tell us in which direction it is pointing.
While it is true that in most cases we will tend to obtain this information or use this functionality for our own turn-by-turn navigation, or through maps, Apple also includes an application called Compass on each iPhone.
It is, as you can imagine, an extremely useful option to know where we are going without having to be forced to install an external app developed by third parties, since our iPhone already has an application designed for this purpose.
