MrSun for iPhone determines where the sun will be at any given time, date, or location. A slider controls the time of day, and shows the direction of the sun (azimuth) and angle over the horizon (elevation) both numerically and visually. If the compass is available, the azimuth gauge will show you the direction of the sun relative to your position at any time. Makes use of GPS to determine location, but the user can use a map to choose a new location anywhere in the world.
