## What is Armillary?

Armillary — your pocket stargazing guide.

Raise your phone to the sky and instantly identify the constellations, planets, and bright stars overhead. Whether you're a seasoned astronomer or looking up for the very first time, Armillary makes stargazing effortless and fun.

KEY FEATURES

REAL-TIME SKY MAP
Powered by your gyroscope and compass, the star map follows wherever you point. Constellation lines and planet labels are clear at a glance.

AR STARGAZING
Open your camera and watch constellation lines and celestial labels overlay the real night sky in real time — what you see is what's there.

SEARCH & NAVIGATE
Looking for a particular star or constellation? Type its name, follow the arrow, and locate your target with ease.

TIME TRAVEL
Drag the timeline to see the sky at any moment, past or future. Relive last night's meteor shower or preview next week's planetary conjunction.

CELESTIAL ENCYCLOPEDIA
Tap any object to see its name, apparent magnitude, distance, home constellation, and more.

ASTRONOMICAL EVENT CALENDAR
Meteor showers, solar and lunar eclipses, planets at opposition... See upcoming astronomical events at a glance, with reminder notifications so you never miss a spectacular sky.

NIGHT MODE
A full red-light filter protects your dark-adapted vision — designed for real observing out in the field.

WORKS OFFLINE
9,000+ bright stars, all 88 constellations, and planetary ephemeris data are built in — no connection needed. Dark-sky sites rarely have signal, and that's exactly what Armillary was built for.

Armillary is inspired by the armillary sphere devised by Zhang Heng, an astronomer of the Eastern Han dynasty (c. 78–139 CE) — one of humanity's earliest models of the celestial sphere. We hope to carry that same curiosity and wonder into the modern age.
