Sky Map – Live Star Tracker

Track ISS passes live on your Lock Screen & Dynamic Island — an astronomy-app first. Plus 8 sky styles, a Moon calendar widget and wrist-guided spotting.

Point your phone at the sky — and know.

Sky Map identifies every star, planet, constellation and deep-sky object you point at, instantly and fully offline. 115,000+ real stars and all 88 constellations render at buttery frame rates, aligned to your exact horizon.

FIRST ON THE APP STORE • ISS Pass Live Activity — a countdown and pass arc right on your Lock Screen and Dynamic Island. Never miss a flyover again. • Meteor-shower peak nights and darkness countdowns as Live Activities too.

THE SKY, YOUR WAY — 8 STYLES Realistic, Chart, Atlas (engraved gold), Red Night, Astro-photo, Aurora, Ink & Paper, Minimal Mono. Your chosen look follows you across the app, all 13 widgets and Apple Watch.

BUILT FOR REAL NIGHTS • True 100% red night mode — protects your dark adaptation on every screen • Stargazing Index: one 0–10 score from clouds, Moon and light pollution • Drag-to-align compass correction + magnetic-interference detection • Stars twinkle. Planets don't. (That's real physics — and how you tell them apart.)

ON YOUR WRIST Wrist-guided ISS spotting with a live bearing ring, a whole-sky dial, a solar-system orrery you can scrub through time, and Smart Stack complications that surface exactly at dusk.

13 WIDGETS Live sky chart, 360° horizon panorama, Moon phase calendar, solar system now, constellation of the day, aurora Kp index, the Sun live from NASA SDO, event countdowns with a one-tap reminder bell, and a red Nightstand mode for StandBy.

HONEST BY DESIGN • Works 100% offline — airplane mode, backcountry, anywhere • No account. Your location never leaves your device. • The free tier stays free, forever. Premium adds depth: the 115,000-star deep catalog, 450+ NGC/IC objects, satellites, comets, event reminders, observation lists with FREE iCloud sync, and every style.

The sky is out tonight. Go look up.
