A planetarium in your pocket
Everything is computed on your phone, in real time, for your place and your moment.
Point and see
Turn on Compass in Settings and the sky follows your phone. Hold it up and the stars and planets in front of you line up on screen.
Tap any star or planet
A card shows its name, constellation, magnitude and distance — even the year its light left — plus colour, temperature and tonight's rise, highest and set times. Bright stars have a short story; planets, their facts.
All 88 constellations
Lines, names and hand-drawn figures for every constellation — from Orion's belt to the faint ones you never noticed.
Planets, Sun and Moon
See where the planets sit along the ecliptic tonight, plus the Sun and Moon, positioned for your exact location.
The Milky Way
Our galaxy stretched across the sky from NASA's Deep Star Maps, just where you'd see it from a truly dark site.
Meteor shower alerts
Optional reminders on the peak nights of the year's major showers — Perseids, Geminids and more.
A quiet, dark interface
Designed to keep your eyes adjusted to the night.
