The app called LightTrac is touted as an excellent one for realtors, but this is an app that many professions will find useful. It provides the direction of the sun at sunrise, sunset and at the exact time that you happen to be looking at the app. It uses GPS to determine your location and displays the sunrise as a yellow line, the sunset as a blue line and the current direction of the sun as a white line, all displayed over a satellite map of your location. Use the slide bar to move forward in time and see where the sun will be on any given day at any hour. It also provides the time of sunrise and sunset for each day of the year in addition to info on moonrise.

While useful for realtors to see where the sun will hit a house at any time of the day, the orientation of home, etc.,  I can think of lots of other ways to use this cool app. It's a great tool for photographers to use to calculate the best time of day to shoot a particular outdoor subject. And architects could find this a valuable tool as well, when evaluating building site orientation. Recreational use might include useful info for campers, cyclists and fishermen. Would love to hear how other people have used this app!

Available for both the iPhone and iPad. Check out the full list of features  here:  http://www.lighttracapp.com/
