Lost? Do not know where the north, and where the south? Use your phone as a compass!
How it works:
Hold your phone face horizontal, and turn so that the top of phone (sun icon) points toward the sun.
To find where the sun is on a cloudy day, hold a pencil or stick upright over a light piece of paper or a lighter part of the ground. The stick or pencil will cast some kind of shadow, indicating the position of the sun.
This app can be used anywhere during the day (from 6:00 A.M. to 6:00 P.M.), when the sun is visible.
The Compass app works best in the fall and winter months, with the worst case behavior in the middle of the year (errors can exceed 30 degrees)
