Star Map: Sky & Star Finder

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 whether it is worth heading out, what is visible and the best time to look
• Read about what you find — 300+ written entries covering the planets, all 88 constellations and their mythology, every Messier object and the brightest stars
• Guided tours — short walks across the sky that show you what to look at and why
• Astronomy calendar — solar and lunar eclipses for your location, conjunctions, oppositions, greatest elongations, equinoxes, supermoons and meteor showers scored for your sky
• Time Machine — scrub to any date and explore the past or future sky
• Map layers — constellation figures and boundaries, asterisms, the Milky Way, coordinate grids, the ecliptic and the horizon
• The real sky — the Moon in its true phase, Saturn's rings, Jupiter's four largest moons, comets, and 150+ satellites bright enough to see
• 9,000 stars and 1,800 deep-sky objects, all computed on your device
• Widgets, an Apple Watch app and a full iPad layout
• Night mode — a red filter that protects your night vision
• No account, no ads. Your location is used to calculate celestial positions. Rounded coordinates are sent to Open-Meteo for weather; Apple uses location for place names and maps.

Free to use, with an optional Pro upgrade for satellites, the full catalogue and calendar, Time Machine, guided tours and more.
