Amber Digital has released MrSun, a free app for iPhone and iPod touch users to determine the location of the sun at any given time, date or place. Using a slider control, users select the time of day and are shown the direction of the sun and angle over the horizon both numerically and visually.
The application can also use the iPhone 3GS compass to display the direction of the sun relative to the user’s current position. Users can get information for their current location using the device’s location services or can choose any other place in the world by selecting it on a map.
MrSun is available as a free download on the App Store..
