iPhone
Astralis turns your phone into a window on the night sky.
Point your phone up and Look Up instantly reveals whatever bright object you're facing — planet, star, or the Moon — rendered as a real, lit 3D sphere with NASA-derived textures, at its true current phase. Save any of them as a full-screen wallpaper.
TONIGHT
A sunset-to-sunrise timeline of everything happening in the sky where you are: moonrise and moonset, planet rise/set times, a stargazing score based on real cloud cover and light pollution, upcoming rocket launches, and visible ISS passes computed with a real orbital propagator — not a canned schedule.
COMPASS
An AR-style compass that points you straight at any visible planet, star, or the ISS, live.
SOLAR SYSTEM
An animated 3D orrery — all eight planets, real relative orbital speeds, real NASA-derived surface textures, starting from today's actual planetary configuration. Tap any planet for its facts. Pinch to zoom, drag to orbit.
EXPLORE
A deep-sky catalog of 30 galaxies, nebulae, and star clusters — real astrophotography for every object, live altitude and rise/set times for your location.
Built with real astronomy: positions are computed locally from NASA JPL orbital elements, not fetched from a third-party ephemeris service. No account required. No ads. No tracking.
