PoleScope AR

PoleScope AR turns your iPhone into a polar-alignment scope for your telescope — and a beautiful almanac of the night sky's culture. It works 100% offline and makes zero network requests.

— POLAR ALIGNMENT, IN AR —
Point your phone at the sky and PoleScope AR overlays the exact position of the celestial pole using ARKit — no need to see Polaris, no compass calibration. Get your equatorial mount roughly aligned in seconds, then refine with the built-in drift-alignment helper for imaging-grade precision.

— PLAN YOUR NIGHT —
A one-tap observing planner ranks tonight's best deep-sky objects for your location, with altitude and magnitude. A coarse Bortle light-pollution estimate helps you judge the sky.

— EXPLORE THE SKY ATLAS —
Pan a live star map of bright stars, constellation lines, planets and deep-sky objects. Tap any object to see its data.

— TODAY: THE SKY'S CULTURE —
A daily card brings the 24 solar terms, traditional festivals, a poetic "star journal," and a situation-drama for your zodiac sign.

— YOUR BIRTHDAY SKY —
See the night sky exactly as it appeared at the moment and place you were born, and discover the lunar mansion the Sun was passing through that day.

— POLESCOPE PRO (one-time unlock) —
A single, non-subscription purchase unlocks the premium star-culture library: constellation and 28-lunar-mansion mythology, NASA / Hubble / Spitzer hero photos of famous stars, the full situation-drama theater, and high-resolution birthday-poster export & sharing. The entire alignment tool stays free forever. Purchases restore on all your devices.

— PRIVACY —
No accounts, no tracking, no analytics, no third-party SDKs. Your location is used only on-device for astronomical math and never leaves your phone.

Clear skies!
