Application for calculating true, magnetic and compass heading.
You can set the course by entering numbers, or by rotating the course wheel, which is much more convenient. The compass heading can be obtained from the mobile.

It is convenient to enter the variation as indicated on the navigation maps, with annual increments, as well as get from the World Magnetic Model by GPS coordinates.
An unlimited number of profiles are available to store the deviation. The average values between the indicated tabular deviation values are calculated using the linear interpolation method.

The application will be useful for skippers, cadets of maritime schools and yachtsmen!
