An offline all-sky map for iPhone and iPad. Raise your phone to the night and read it like a chart — stars, constellations, planets, and everything below the horizon.
Original artwork resolves over every one of the 88 IAU constellations as you select it.
Scrub through hours, months, or years and watch the whole sphere rotate in real physics.
Over a million Gaia DR3 stars render smoothly — deep enough to feel like true darkness.
The full sky ships inside the app: catalogs, constellation geometry, artwork, ephemerides, and the horizon model are all offline and deterministic. No account, no ads, no tracking.
A north-anchored horizon silhouette separates the atmosphere-tinted sky from a dimmed lower hemisphere — so you can keep exploring what is still below the horizon instead of losing half the universe at your feet.
The visible sky follows the Sun continuously from clear daylight blue into the indigo of night.
