Golden Hour, Property Sun, AR
Free · Designed for iPad. Not verified for macOS.
Sunio transforms how you experience sunlight. Watch the sun's journey come alive with dynamic 3D lighting on real terrain—the only app that animates how light and shadows change throughout the day. Plan property purchases, capture golden hour photography, and optimize solar panels with professional-grade accuracy.
SEE SUNLIGHT TRANSFORM YOUR WORLD
Press play and watch landscapes transform with solar-accurate lighting. Sunio's 3D animation engine shows exactly how sunlight and shadows move across terrain throughout the day. Scrub through time and see building shadows shrink at noon, stretch at sunset, and disappear after dark.
Perfect for evaluating property sun exposure before buying a home. See which rooms get morning light, where afternoon shadows fall, and how seasonal sunlight changes throughout the year.
PERFECT FOR PHOTOGRAPHY
Never miss golden hour again. Sunio calculates precise golden hour, blue hour, and twilight times for any location on Earth. See exactly where the sun will rise or set with AR overlays that show the sun's path through your camera view.
The interactive timeline lets you scout locations remotely—scrub through an entire day in seconds to find perfect lighting conditions.
MAKE SMARTER PROPERTY DECISIONS
Buying a home or apartment? Sunio reveals crucial sunlight information that photos and tours miss. Check if your balcony gets afternoon sun. Verify if morning light reaches the bedroom. See how neighboring buildings cast shadows on your property.
Real estate agents use Sunio to showcase property features—demonstrating southern exposure and natural light advantages. Garden planners identify full-sun zones for vegetables and shade areas for plants.
PROFESSIONAL TOOLS
Sunio delivers professional-grade sun tracking with NOAA algorithm accuracy. Architects use it for daylight analysis and shadow studies. Solar installers optimize panel placement by visualizing solar angles throughout the year.
Get precise solar data: azimuth, elevation, sunrise/sunset times, solar noon, twilight phases, and day length. View sun paths as 3D arcs overlaid on satellite imagery or through AR on your camera.
Building shadows appear realistically on 3D terrain—see how structures cast shade on courtyards, streets, and neighboring properties.
