Trace your skyline over a photo and see exactly how many hours of direct sun a spot gets, through every season. Built for gardens, greenhouses, and sites. Know the sun before you build, plant, or place a panel. Deconstruct Sun turns your phone into a solar site-analysis tool. Stand where a garden bed, greenhouse, patio, or solar array will go, trace the buildings and trees on the horizon, and get the number that actually matters: how many hours of direct sunlight that exact spot receives, today, at the solstices, and at the equinoxes. It works the way a designer thinks. The sun's path is drawn as an arc across a sky chart; your obstructions are a skyline you paint over it. Where the sun clears your skyline, it shines. Where a building or a tree blocks it, it doesn't. The math is honest, a five-minute-step calculation over the real solar geometry for your latitude and date. TRACE THE REAL HORIZON Don't guess the skyline, trace it. Photograph the view, or import a wide shot, and paint the obstructions directly over your own photo. A guided sun-arc sweep walks you through a few framed shots that follow the sun's band across the sky, and a live overlay projects the sun's path onto the camera so you can see where it will travel before you capture. SEE THE WHOLE YEAR One tap shows direct-sun hours for the summer solstice, winter solstice, and both equinoxes, and today, so you can tell a spot that bakes in June but goes dark in December, from one that works year-round. SHARE A REAL STUDY Export a clean, branded PDF sun study for a client or your own records, or share a photo-real composite of the site with the sun arcs drawn over your skyline.
