See realistic 3D shadows cast by mapped buildings at any time of day, in any season.

See realistic 3D shadows cast by hills, ridges and valleys as the sun moves across the day — not just a static shaded-relief map.

Preview planned buildings before they go up and see exactly how they'll change light and shadow in nearby streets, parks, and apartments.

Overlay the sun’s path on a Street View panorama to scout the light at a distant location before you visit.

All the sun data you need for any date and location: times for sunrise, sunset, golden hour, blue hour, and every twilight phase — plus azimuth, elevation, shadow ratio, and total day length.

Hourly cloud cover layered with sun position data — spot the clearest window for shooting, planning, or just catching a perfect sunrise.

Live sun data from your home screen — track current elevation, azimuth, and shadow ratio, or check today's sunrise, sunset, and key light times at a glance.

Set an alarm or notification for sunrise, sunset and other sun events, tailored to the moments you want to catch.

Learn moreSuch a useful app for planning shoots! I use it to figure out where the light will hit, and it’s super accurate. The AR view is awesome, and it’s saved me plenty of guesswork when chasing golden hour. Simple, reliable, and a must have if you care about good light.
I love how this app simplifies setting a routine of being out in the light of the sun at the most optimal times of the day! Best app on my phone currently!
Used it while checking apartments and it was surprisingly helpful to see how sunlight would hit the rooms.
I absolutely love SunCast! I use it here in Australia, around Bondi, and it has become one of those apps I didn’t realise I needed until I had it. … The visualisation is fantastic, it’s easy to use, and it’s surprisingly accurate. A genuinely brilliant app — practical, clever and beautifully useful. Highly recommended!
Very good for finding the right place for photovoltaic panels.
I only really need the app when I’m at a gig and need to plan my shot, but it has worked amazingly for that purpose! I can see where the sun will be when I’ll be taking photos and plan accordingly. Super simple and easy to use.
Great app, I’m so glad it exists.
Soy arquitecto y, para mi profesión, el movimiento aparente del sol es importante.
Handy when planning hikes or picnics. I can see where shade will be.
I like it.
Golden hour, blue hour, shadow direction, sunrise and sunset… You can even plan ahead for another city and a future date. It’s cost-effective for photography trips.
Showed me the sun patterns in my yard so I could place plants smarter. They're already doing better.
This is the only app one really needs on a phone.
Helps a lot with planning shoots. I can check light direction before heading out, which saves time.
It’s really helping me to figure out a solar panel setup for my garden. Worth the money.
Have been using it to plan my garden and it works great.
It does all that it needs to do. I had been looking for this. Great!
Helpful when viewing places
Amazing.
Rien à redire. Fonctionne très bien.
