StarTrail: Stargazing

StarTrail turns your phone into an AR window on the night sky.

Lift your phone and StarTrail overlays the stars, planets, constellations and the Moon exactly where they are — all computed on-device, so the core works with no internet and no account.

• AR Sky View — point at the sky and identify what you see
• Sky Map — pan and search the whole sky any time
• Tonight — what's visible now, moon phase, twilight times
• Events — meteor showers, conjunctions, eclipses with reminders
• Dark-Sky Planner — light-pollution map and the best spots to escape city glow
• Observation Log — record what you saw, with photos

No server, no tracking. Your location stays on your device.
