Point your iPhone at the night sky — and know exactly what you're looking at. Cosmo Lens is a real-time star map and AR sky tracker that identifies stars, planets, constellations, satellites, and galaxies the moment you aim your phone at them. Built for stargazing beginners and seasoned astronomers alike — and it works fully offline, even at remote dark-sky sites with no signal. YOUR PERSONAL PLANETARIUM - Identify what's above you instantly: aim your iPhone and the sky map follows your every move. - AR mode with Sky Blend: see constellations drawn over your live camera view, and swipe to fade between the real sky and the map. - Explore nearly 100,000 stars, all 88 constellations with stunning hologram artwork, the full Messier catalog, and thousands of NGC/IC deep-sky objects — galaxies, nebulae, and star clusters. - Night mode with red-light filter protects your dark-adapted eyes in the field. TONIGHT'S SKY, SCORED - A nightly Sky Score (0–100) tells you at a glance if it's worth going out, combining darkness, moon brightness, cloud forecast, and a built-in light pollution atlas. - Get tonight's best picks: visible planets, ISS passes, meteor showers, and rare events — plus a week-ahead outlook. - Add the home screen widget to check tonight's score and upcoming events without opening the app. TIME TRAVEL THROUGH THE SKY - Jump to any date — past or future — with a cinematic animation. - Preview solar and lunar eclipses, planetary conjunctions, planet parades, and supermoons before they happen, then scrub hour by hour around the event. MOON & ECLIPSES, MAPPED - A complete moon calendar with phases, illumination, rise and set times, and the traditional names and folklore of every full moon. - Watch the Moon's arc glide over a 3D map of your real surroundings, and trace upcoming solar eclipse paths on the map. TRACK EVERYTHING THAT MOVES - Follow the ISS, Hubble, and over 150 visible satellites in real time. - Never miss a meteor shower, bright comet, or eclipse with smart notifications tuned to your location. - Planets rendered with real detail — plus asteroids, comets, and even Jupiter's four largest moons. AN ENCYCLOPEDIA IN YOUR POCKET - Tap any object for photos, key facts, and stories: from Saturn's rings to distant nebulae and black holes. - Search anything — "Andromeda", "M31", "ISS" — and let the arrow guide you straight to it in the sky.
