Will this flat get sun in winter, or bake on summer afternoons? See the whole year for any window, set on the map or by compass. One-time purchase. See where the sun comes into your room: today, at midsummer and at midwinter. Hold your phone up to a window. Sunlight measures which way it faces and what’s across the street, then shows the patch of direct sun on the floor, hour by hour. No compass? Set the direction by hand. Know before you rent or buy whether that flat will get morning sun, or none at all in winter. The room in the pictures is a sample room. Times and direction are calculated for your window; how far the sun reaches into the room is estimated for a typical full-height window. • The real sun for your window: when direct sun starts and ends, and how far into the room it reaches • The whole year in one line: the weeks with little or no sun, and summer afternoons with strong sun • Set the window direction on a satellite map, or check your compass reading against it • Compare homes: rank the places you’ve viewed by winter sun or summer shade • Morning, afternoon or evening sun, and a warning for strong afternoon sun in summer • Every room of the home: add a window for the bedroom, kitchen or office and compare them • Search other addresses to check a place before you visit • Share a sun card with your partner, landlord or agent Free: one place, today’s sun, one window, the year in words, and the map. Full: any address, exact dates and hours all year, summer & winter views, every room, compare homes, share cards. Sunlight Full is a one-time purchase: no subscription, no account, no ads. Everything is calculated on your device.
