Discover what's visible in the night sky tonight — right from your backyard. SkyChecker uses NASA's Jet Propulsion Laboratory data to show you exactly which celestial objects are visible from your location.

The app automatically determines sunset and sunrise times, then shows you only the objects that will be above the horizon during nighttime hours. PERFECT FOR • Casual stargazers curious about tonight's sky • Amateur astronomers planning observation sessions • Educators teaching astronomy concepts • Anyone who's ever looked up and wondered "what's that?" PRIVACY FOCUSED Your location stays on your device. We don't track you, collect personal data, or show ads. The only external connection is to NASA's public astronomical database. Clear skies!
