Description
Stellar Tour is the only AR stargazing app written by an astrophysicist. Point your phone at the night sky and get a guided tour of everything up there: two billion real stars, every planet and major moon, eclipses, meteor showers, and 13,000 deep-sky objects.
Astrophysicist Dr. Aaron Day wrote every word. Instead of the standard flood of random facts, Stellar Tour tells the scientifically accurate story of each world: what it is like on the ground, in the seas, or floating through the clouds.
THE NIGHT SKY, FOR REAL
Two billion stars from ESA's Gaia survey, each in its true position. Pinch to zoom from your backyard to the galactic core.
The Milky Way as it actually looks, with constellations, planets, and satellites overlaid on your live sky.
Night Vision mode keeps your eyes dark-adapted with a pure red display.
ECLIPSE EXPLORER
Simulate any solar or lunar eclipse from your exact location: local timings, a disc animation of the Moon crossing the Sun, and a live countdown. Built for the total eclipse of August 12, 2026.
PLAN YOUR NIGHT
Sky Calendar: every eclipse, meteor shower, conjunction, and full moon. The week ahead is free; the full year comes with the expansion.
Night Planner: the best targets for your sky tonight, hour by hour. Cloud cover from the weather forecast is reported so you can plan ahead.
Reminders that fire only when something is worth stepping outside for, including the International Space Station and Tiangong Space Station passes with a live countdown.
GO DEEPER
Telescope Catalog: 13,000 NGC, IC, and Messier objects, searchable and shown on your sky.
Exoplanets: nearly every known world, in its actual position on the sky, with sizes, temperatures, and orbits.
The Solar System up close: planets and major moons in NASA probe imagery, in visible light, ultraviolet, infrared, and radar. Rotate them to any angle.
FOR EVERYONE
Kid Mode rewrites the whole tour for young explorers.
Birthday Sky: a shareable card of the sky on the night you were born.
Smart search: ask for exactly what you want.
Take the Stellar Tour!
