What it tells you
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.
What it watches for
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.
