GoldenHorizon

GoldenHorizon is a sun, moon, and sky planner for outdoor photographers, hikers, drone pilots, eclipse chasers, astronomy enthusiasts, and anyone timing work around natural light.

The app computes planning data locally so you can understand the next light window, moon condition, sky event, or shadow direction before you head out.

Core tools:
- Today view for sunrise, sunset, twilight, golden hour, and blue hour
- Moon phase, illumination, moonrise, and moonset details
- AR-style sky arc planner for lining up a scene
- Eclipse, planet, ISS, meteor, aurora, and Bortle references
- Milky Way visibility scoring
- Star-trail and timelapse planning calculators
- Photographer mode for focal length, field of view, and alignment work
- Shadow and drone-shadow planners for sun-angle decisions

GoldenHorizon uses established solar, lunar, and sky-position formulas for practical field planning. It is built for fast decisions: where to stand, when to wait, and what the light will do next.

Saved locations and plans stay on the device. Location access is used to compute local sky data. Camera access is used only when the AR sky planner is opened.
