Star AR Traces

StarTrace turns your iPhone or iPad into a window to the cosmos. Point your device at the night sky and watch constellations come alive in augmented reality, with lines, labels, and star data overlaid on the real sky. **AR Sky View** Use your camera with gyroscope and compass to see constellations exactly where they appear in the real sky. Stars are rendered with accurate colors based on their spectral type — blue giants, yellow dwarfs, red supergiants — all in their true positions. **24 Constellations & Growing** Explore major constellations from every season — from Orion's winter brilliance to Scorpius's summer glow. Each constellation includes accurate star positions (J2000 epoch), constellation lines, and detailed information. **Mythology from Three Cultures** Every constellation comes with stories from Greek, Arabic, and Chinese astronomical traditions. Discover how different civilizations saw the same stars and created vastly different legends. **Tap for Details** Tap any constellation to see its info card: Latin, English, and Russian names, brightest star, area in square degrees, season visibility, and a full list of stars with magnitudes and coordinates. **Night Mode** Red-filtered interface preserves your night vision. One tap switches the entire app to a dark red theme designed for stargazing in the dark. **Native iPad Experience** On iPad, StarTrace uses a sidebar layout with constellation browsing by season, direct navigation to any constellation, and a full detail view — not a stretched iPhone app. **Fully Offline** All star data, constellation lines, and mythology texts are stored locally. StarTrace works perfectly in remote locations with no cell service — exactly where the best stargazing happens. **No Subscription. Ever.** One purchase, everything included. No ads, no in-app purchases, no data collection.
