SkyTonight

Know what to
see each night.

Naked-eye astronomy, tailored to your sky.

ARRIVING SOON - iOS

Go now. The sky is open and conditions are good — step outside.
Soon. Worth waiting for — your window opens later tonight.
Maybe. Possible, but conditions are mixed — your call.
Not tonight. Clouds, glare, or daylight are in the way — rest easy, check back tomorrow.
Planets The five you can find without a telescope.
The moon Phase, glow, and how much it washes out everything else.
Bright stars The dozen or so that cut through any city's glow.
Your sky Cloud cover, light pollution, moonlight, how dark it actually gets where you stand.

Then it tells you, in four words or fewer, whether tonight is one of the nights worth looking up for.
