RealTime Space

Fly a real-physics starship through the whole solar system and 8,920 real stars. Free for 60 days, then one $0.99 unlock keeps the universe forever. No subscription.

Strap in. RealTime Space puts you at the helm of your own starship in a photoreal, full-scale universe — every planet, every major moon, and 8,920 real stars, all in the palm of your hand.

FLY ANYWHERE Real navigation physics with thrust, drift and 100x warp. Skim Jupiter's storms, cruise through Saturn's sunlit rings, chase comets across the system, or point the nose at a star and just go.

A REAL SKY Every star you see is real — 8,920 naked-eye stars with their true names, brightness and 3D positions, plus the Milky Way band exactly where it belongs. Fly to Sirius, Betelgeuse or Vega and watch a point of light resolve into a blazing sun.

THE WHOLE SOLAR SYSTEM All eight planets in photoreal detail, the Moon, volcanic Io, icy Europa, hazy Titan, Enceladus and its geysers, the asteroid belt, famous comets, deep-space nebulae — and Sagittarius A*, the black hole at the center of the galaxy.

THREE WAYS TO FLY VISOR — a clean, unobstructed view of space. HELM — a full cockpit around you. CHASE — follow your own ship from behind.

SCAN AND DISCOVER Scan planets, moons and stars to fill your Field Guide, track your journey on the Space Map, and complete missions as you explore.

MADE TO FEEL REAL Analytic eclipse and ring shadows, real star colors, a procedural engine soundscape, and a sky accurate enough to learn constellations from.

FREE FOR 60 DAYS Everything is free for your first 60 days. Keep the whole universe forever with a single $0.99 unlock — no subscription, no ads, no account, no data collection.
