Fantastic app for planning for where the natural lighting will be.

This is a fantastic app for knowing where the natural lighting will be. Super easy to understand and to use. Obviously extremely useful for photography lighting choices, but has many other uses as well. At any day / time of the year you can figure out where the sun will be shining, inside and out. This is great for interior design, including wall, drapery and furniture color choices, to placement of various furniture and activities within a room. Planning a wedding for next June, make sure the Bride and Groom are neither squinting, nor in the shade. This app showed us just how good our guesses were for where we placed shade trees on the south side of our house after moving in. Next time, we won’t have to guess - we can figure out exactly where will be best. Great for pool and sun-dependent landscaping choices. Great for architects to get a quick idea of how they might site their building, well before getting into too much building detail or spending bucks doing full annual computer sun simulations. Great for HVAC Contractors and Engineers (me) for doing initial airflow balance planning. Great for astronomy buffs and general science nerds!! Helps me know when I can expect to let my cabin-fevered cats out on the back deck in early spring. Love it! Will support this app forever!! Thanks!!

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).
