The Best by far!

LightTrac is by far the best way for anyone who wants to envision, actually see, and follow all the details of how the sun effects your home, vacation place, sailboat, or anywhere as the Sun rises in the east (in precise degrees on compass), elevates in degrees, during the day, sets, and the duration of various models of darkness.

For anyone interested in the place and environment on land or sea, “Don’t leave home without LightTrac”!

Great app - I use it regularly

Update - I still really like this app and its simplicity. I have all the other more expensive and complex apps, but I still visit this one first. My previous comments still apply, it would be nice to see a few changes:

Still worth it. But would benefit from having buttons, such as locations, more intuitive. Interface still a little clunky and doesn’t seem to take full advantage of later iOS versions. I would be willing to buy it again, I’ve had this app since my first iPad (1).

Tool for photographers

I use LightTrac to see where the sun is and at what angle for photo shoots at different times of the day. It has definitely helped with the planning. I have also used it when family members were going to build a house and hey wanted to see where the sun would be at various times of the year.
