iPad app for location photography

Hey friends, I tried a new app for iPad called LightTrac and I found it to be very useful. It's designed for photographers to find ideal hours to do their outdoor shoot by tracking the Sun's elevation and position at any time in any location. No learning curve to operate. Here is the appstore link http://itunes.apple.com/us/app/lighttrac-for-ipad/id363963108?mt=8
