Astar turns the real night sky above you into a place for memory. Point your phone at the sky, or explore freely with a swipe, and see a live 3D star map of roughly 1 million real stars plus the Moon and planets, rendered from real astronomical data and tilted to match your exact location. Tap any star to read the notes left there, or leave your own. Some notes are public and appear in the Explore feed; others stay private in your personal Journal. WHAT YOU CAN DO - See the real night sky in 3D, oriented to where you're standing - Find constellations overhead, drawn with constellation lines and 3D figure art - Tap a star to leave a short note, text only - Browse Explore, a public feed of notes other stargazers have left under real stars - Like and favorite notes that resonate with you - Keep a private Journal of your own notes and favorites, with a private star map just for you - Give an unclaimed star a name: a symbolic, community-given dedication shown to everyone in Astar's sky, a personal way to mark an anniversary, a memorial, or a birthday. This name lives within Astar's own community catalog only. It is not an official astronomical designation and is not recognized by the International Astronomical Union or any scientific body. A plain language disclaimer is shown before every naming purchase. - Aim your phone at the sky in Capture mode to line up on the nearest bright star FREE TO USE Astar's core experience is free, with no time limit: view the live sky, browse Explore and your Journal, and post one public note and one private note every day.
