Put the real sky in your hands. Constella is a living map of more than 1.8 billion real, cataloged celestial sources. Every point of light you see is anchored to measured catalog or orbital data—not decorative filler added to make the sky look busier. The entire experience is free. No ads. No subscription. No paywall. No “Pro” or “Plus” tier. The universe in Constella is open from the first launch. EXPLORE THE REAL SKY Point your iPhone or iPad toward the heavens and move through the sky around you. Find stars, constellations, planets and moons; follow comets, asteroids and real satellites; travel through time; or choose any city on Earth. Search by familiar name or catalog designation, then open an object to discover live rise and set times, photography, facts and a story worth staying for. MAKE THE SKY YOURS Finish an object’s story and stamp the visit in your Sky Passport. Build a personal My Sky, save favorites, watch worlds you want to return to, collect milestones and decide whether each new stamp is Public, Friends or Only Me. SHARE WONDER, NOT NOISE Send a friend a Sky Postcard that preserves the exact object, time and view. Leave a Note in the stars for another explorer to discover at that place in space. Give a community name to a star. Finish a Story and leave Public stamps on two days to qualify for a Luminary title, then defend it with your rolling 30-day score. DESIGNED FOR CURIOSITY The core sky and stories work without an account. Sign in with Apple is optional and unlocks syncing and community features. Location is optional too: use your current sky for local orientation and rise/set calculations, or choose a city instead. Motion, location and notification controls remain yours. Constella has no advertising tracker and does not sell personal information. Community content can be reported, people can be blocked, and an account and its associated data can be deleted inside the app. The sky is enormous. Your place in it can still feel personal.
