Sunlight Tracker is a temporarily free app for iPod Touch/iPhones. It is a simple but very useful program with the following features (copied from Apple’s website):
Find out sunrise, sunset, twilight times and day length for any day and location.
Easily track Sun’s position and elevation at any time of day for any location. Use it to find the perfect time for photographing your subjects.
Using Google map, zoom into a spot and then find the direction of sunlight at that spot for any time of day. For instance, you can find out which direction the sun would hit any landscape or a lake or a waterfall or any outdoor subject for that matter and it helps you plan to visit these locations at the right time for best photographic opportunity.
Save multiple locations and switch between them easily.
Does not require internet connection for basic functions, so you can take the app anywhere and use it any time. Internet connection is only required when adding a new location, or when using search or using the maps.
Works on both iPhone and iPod touch.
Get it while it’s still free!
