LightTrac for iPad is a simple application that shows the sun angle at a given location at a specified time of day. Colored lines showing sun angle at sunrise, sunset, and the specified time are superimposed onto a Google map. The map can be toggled from regular to satellite mode.

This is a great tool for anyone shooting outdoors or indoors with available light. I recently used this to plan ahead for a wedding shoot. I knew the time and location of the wedding, and pulled the scene up in LightTrac to get a feel for where the shadows would be, and where to place my strobes. Of course I also visited the site before the wedding, but getting a top-down view of the setting before going onsite was very helpful.

At USD $3.99, outdoor shooters can’t go wrong with this app!
