Stellara turns your phone into a window on the sky above you — right now, from exactly where you're standing.
POINT YOUR PHONE AT THE SKY
AR sky mode overlays the Sun, Moon, planets, stars and live satellites at their true positions. Hold your phone up and the sky labels itself. Works in daylight, and works offline.
NEVER MISS A LAUNCH
Every upcoming rocket launch with a live countdown, the rocket, the pad and the mission — plus a push alert the moment it goes live. Watch the stream inside the app.
THE SKY, IN REAL TIME
A 3D map of the sky at your location: stars coloured by spectral class, all 88 constellations, planets at their true positions, and thousands of satellites overhead. Scrub time forward and back to see what's coming.
NEAR-EARTH OBJECTS (NEO) & SPACE WEATHER
Close approaches sized against things you can picture, impact-risk ratings straight from NASA/JPL, the Kp index, and whether the aurora might be visible from your latitude tonight.
THE CODEX
Rotatable 3D planets, thousands of exoplanets, live rover photos, and everyone who is in space right now.
DAILY COSMOS
NASA's Astronomy Picture of the Day, plus a searchable library of NASA photography and video.
REAL DATA, FROM THE PEOPLE WHO COLLECT IT
Stellara doesn't invent anything. Every number in it comes from a public source — NASA, JPL/CNEOS, NOAA Space Weather Prediction Center, The Space Devs, Celestrak, SIMBAD/CDS and the NASA Exoplanet Archive — and every one of them is credited in the app.
YOUR LOCATION STAYS YOURS
Stellara uses your location to place the sky correctly. It is processed entirely on your device and is never sent to us, to advertisers, or to anyone else. The camera is used only for the live AR view — frames are never recorded, saved or transmitted.
Stellara is free and ad-supported. Stellara Pro removes every ad and unlocks the premium extras — the 3D Earth & Moon globes, Find-it AR guidance, and the radio, re-entry and deep-space tools.
Not affiliated with or endorsed by NASA, JPL, NOAA, or any space agency.
