Sun Compass & Sunrise/Sunset 3.4c
the author of this app says:
This compass has a new formula to calculate north with 100 percent accuracy. The program also displays several sun angles. Turn your Pilot directly toward the sun, and you will see where north is on the screen! The direction is updated every minute.
Before you begin, you have to input the following values: longitude, latitude, time zone and Daylight Savings Time.
This application is now in color too!
