Compass widget can be put on the home screen with the following features:
- Different styles
- Customizable text sizes and colors
- Text inside can show speed altitude direction and other
- Rotatable arrow or background
Direction can be detected based on two types:
- Satellites (GPS). You need to move forward for several meters to detect the direction properly. This is the most useful type for auto.
- Magnetometer. Some devices may not have a magnetometer or may not be supported.
