Court Shade, a sunlight map for one tennis court

Field notes

The workflow uses a phone at the net: the player turns once while the device records the surrounding skyline, then the app combines those angles with solar calculations for the full year. The page says the reading remains on the phone and takes under a second to process. Its model accounts for more than tree shade, including sunset, winter sun, and glare down the court. A future one-off price and branded maintenance-firm offering are mentioned, but neither has been set.
