Velastar is a native iOS sky atlas built with Metal and a testable Swift astronomy core. Point your iPhone at the real sky, explore 8,002 Hipparcos stars and all 88 constellations, move through time and location, or change your observing world entirely. Land on the Moon, Mars, or Europa to see local horizons, solar time, planets, and moons. It also includes a 3D Solar System, offline object guides, Milky Way planning, light-pollution tools, world clocks, and six astronomy widgets.
