Suncheck

How much sun does this spot actually get? It’s a question people ask at almost every flat viewing, but rarely get a reliable answer to. Take a photo from a balcony, window, or garden. Suncheck maps the skyline and shows how the sun moves across that exact view throughout the year. You can see how many hours of direct sunlight you get each month, which buildings or trees block it, and how much sunlight each one costs you. SAM 3.1 identifies the sky and surrounding objects. Our own calculations handle the sun's position, camera alignment, skyline measurements, and sunlight tracking. The result is calculated minute by minute for the 21st of each month. Muse Spark 1.3 provides the plain-English verdict and answers questions about the location. The photo becomes an interactive view of your own sky. Watch the sun move across it, see where it's blocked, and explore the monthly sunlight hours and the impact of each obstruction. You can take a photo with your phone or import an original image. Suncheck also tells you how much of the horizon it could analyze, since results only cover the directions visible in the photo.
