Day & night map

Essential data tables

Purchasing Solar Shades for New House

"We bought a new house in the desert. Selecting the correct solar shades is largely about understanding sun position during the summer. This app was PERFECT. Just select the day of the year and then point the camera out the window. The app superimposes the sun track and notes the position at different times of the day. Every window-covering designer / sales person should have this."

Very well-designed

"Shows the position of the sun at any time throughout the day. A really great app. Very well-designed and written. I actually was only looking for something to show the angle of the sun above the horizon, because I like to wait until it’s only 30° or lower in the summer, to avoid sunburn. This app does that and a lot more."

Amazing app

"Very accurate!!! Very helpful when I work on my videography, and it’s free? You can’t beat that! Thank you!"


"Within 1 minute of using I’m beyond impressed. Excellent app!"
