AstraLoc

AstraLoc shows the sky in augmented reality. Open the app, point your iPhone at the sky and see where the Sun, the Moon, the planets, the bright stars and the Milky Way are — or will be — from where you stand or from any place you choose. Built for landscape and astro photographers who need to know where the light will be before they get there. TIME TRAVEL WITH A SWIPE Swipe left or right to move through hours and days. Watch the Sun travel its daily path, the Moon rise in its real phase and the Milky Way core climb above the horizon. SUN • Animated Sun and its full daily path across the sky • Sunrise, sunset and solar noon • Golden hour and blue hour, civil, nautical and astronomical twilight on the timeline MOON • Moon drawn in its real phase and position • Moonrise, moonset and illumination • Moonlight and moonless periods shown on the timeline NIGHT SKY • Milky Way band, with the galactic centre visibility window for the night • Planets with real textures, and the brightest named stars • Night rating: how dark and moon-free each night is, shown on the calendar with the best nights of the month ECLIPSES • Solar and lunar eclipses for your location, marked in the date picker • Tap an eclipse day to jump straight to greatest eclipse ALIGNMENTS • Aim at a landmark, pin the direction and find out when the Sun or the Moon will line up with it — perfect for a Moon behind a lighthouse or a "henge" sunset down a street PLACES • Save your photo spots and pick new ones on a map • Light-pollution estimate for each place, with a sky-brightness map overlay • Times shown in each place's own time zone Requires an iPhone with ARKit. Location is used only to calculate the sky for where you are; it is never stored or shared.
