About this app

See when direct sunlight can reach the room where you live, work, or grow plants. Sunnook turns the room dimensions, windows, north, date, and location you review into an interactive clear-sky sun preview. PLAN AROUND THE SUN - Scrub through the day to see where modeled direct light can land. - Explore direct-sun opportunities across dates and seasons. - Save Sun Pins for favorite spots such as a desk, chair, or plant. - Choose optional local reminders before a modeled Sun Pin interval. BUILD A REVIEWABLE ROOM MODEL - Start immediately with Sunnook's sample room. - Draw a room from measurements on any supported device. - Use a photo as visual reference while keeping scale, windows, and north editable. - On compatible LiDAR devices, use Apple RoomPlan to scan a room, then review every dimension and opening before saving. UNLOCK SUNNOOK PRO Free access includes the sample experience and one saved room. One lifetime in-app purchase unlocks unlimited saved rooms, the annual Sun Calendar, printable Light Maps, eight-second sun time-lapse exports, and modeled Sun Pin alerts. Purchases are handled by Apple, and Restore Purchases is available for the same Apple Account. KNOW WHAT THE MODEL INCLUDES Sunnook models theoretical direct sunlight under clear-sky conditions. It does not include clouds or live weather, exterior buildings or trees, curtains, glazing loss, tint, or reflected brightness. Treat the result as a planning opportunity, not a promise that a room will be bright. PRIVATE BY DESIGN Room models, photos, measurements, scans, and sunlight calculations are stored in local app storage. City searches and place names use Apple's Maps service. Optional TelemetryDeck analytics stay off unless you choose to share them, and can be turned off again from Privacy & Analytics. No Sunnook account is required.
