Lookup: Tonight's Sky
Find tonight's constellations
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
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.

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
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.
