A simple compass that can measure eight directions. Displays the eight directions to study in elementary school. If a magnet is used in the tablet case, it may not point properly. In that case, tap the "Set current front as north" button. Forcibly sets the direction at the top of the screen as north. It's the perfect feature for learning about orientation in school lessons.
