Lookup: Tonight's Sky

About this app

Tonight, look up. Lookup computes tonight's sky from your location and today's date, showing which constellations, planets and the Moon are up — fresh every night. SKY SCORE FOR TONIGHT Blends the Moon's phase and altitude, the length of full darkness and cloud cover into a 0-100 score for how good stargazing is tonight — plus the darkest "prime window." LIVE SKY MAP The sky right above you, right now. Stars, constellations, planets and the Moon in a fisheye projection — slide time to watch the sky turn. POINT AT THE SKY (CAMERA + COMPASS) Aim your phone at the sky and the names of constellations and planets in that direction overlay the real sky. Instantly answer "what's that bright star?" OBSERVATION LOG & STAMPS Tap a constellation, planet or meteor shower you've seen to log it — they collect like stamps. See how much sky you've met this month. WORKS OFFLINE Sun, Moon and planet positions are computed on-device, so it works without a connection. Only cloud data uses free weather data.

It does not provide astrology or fortune-telling. The Sky Score is a guide; the real sky varies with air, light pollution and terrain.

Fixed a bug where saving a far-away observing location could show a high sky score on an empty report. Tonight's sky is now computed correctly for the location's longitude, and shows an honest 'No data' state when there's nothing observable.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
