About this app

Point your phone at the night sky and instantly identify any star, planet or constellation. Your iPhone becomes a pocket planetarium and a personal stargazing guide. • Point & identify in AR or Map mode — a live sky map labels every star, planet and constellation • Tonight — a Stargazing Index (clouds, Moon, darkness) tells you if it is worth heading out, what is visible and the best time to look • Astronomy calendar — moon phases, meteor showers, ISS passes, sunrise, sunset and twilight • Time Machine — scrub to any date and explore the past or future sky • Object paths — altitude curves and the best viewing time • Night mode — a red filter that protects your night vision • 9,000+ stars, the planets, the Moon and deep-sky objects, all computed offline • Privacy-first — your location never leaves your device. No account, no ads Free to use, with an optional Pro upgrade for satellites, the full calendar, Time Machine and more. Star data: HYG Database (CC BY-SA). Constellations: Stellarium.
