Is the sky worth turning up for?

Undrlit forecasts each sunrise and sunset at your places, and tells you whether it's worth being there, and why.

How it works2 / 3

Cloud above you, and a clear path to the sun.

At its best, the sun is below the horizon, lighting the cloud above you from underneath. That light crosses 200–350 km of sky first, and low cloud out there can block it. Undrlit checks both.

Tell Undrlit where you shoot and it'll forecast that sky.
