Armillary vs SkyScope

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.

SkyScope is free to download and works without an account. Take or import a night-sky photo for an AI-assisted identification. No AR calibration or compass setup is needed. WHAT'S INSIDE • Scan: take a new photo or import one from your library; see the primary constellation, confidence explanation, object counts, named stars, and a concise astronomy fact • Compare candidates when the visual match is uncertain • See location and time as observation context, separate from the visual estimate • Explore tab: browse planets, stars, constellations, and deep-sky objects by category FREE RESULT shows the primary constellation, stats, an astronomy fact, and the first two named stars. Premium adds observing context, all named stars, planet candidates, and moon details when detected. IMPORTANT SkyScope is an astronomy and reference app — not an astrology app. Results are estimates; use the suggested photo and candidate checks before treating a match as certain. Premium is available as a Weekly Premium auto-renewable subscription or Lifetime Premium (one-time purchase), depending on your App Store region. Prices may vary by country or region.
