Look up at the right moment. OrbView turns your phone into a live window on everything orbiting overhead — the International Space Station, Starlink trains, rocket bodies, and hundreds of satellites you can see with your own eyes. No telescope. No jargon. Just open the app and find out what's crossing your sky tonight. SEE WHAT'S ABOVE YOU, LIVE • A real-time 3D globe shows satellites moving over your exact location right now. • Color-coded by type: the ISS, Starlink, weather and science satellites, rocket bodies, and more. • Tap any object to see where it is and where it's headed. KNOW EXACTLY WHEN TO LOOK UP • Your feed lists upcoming passes with countdowns, direction, and how bright each one will be. • The Sky Score tells you, at a glance, how good tonight's viewing is. • Spot the station and catch a Starlink train while they're actually visible. GET ALERTED BEFORE IT HAPPENS • Flag any pass and OrbView notifies you minutes before it crosses your sky. • Wake up to a morning Daylight Brief of the best passes coming tonight. • Never miss the ISS gliding over your backyard again. GO DEEPER • Full Intel cards tell the story behind every object — what it is, who launched it, and what it does. • Log the passes you spot, build a streak, and earn badges as you go. OrbView is free to use. Upgrade to Pro to remove ads, unlock pass alerts, and read Full Intel on every satellite. Satellite positions are calculated from public orbital (TLE) data. OrbView uses your location only to compute which passes are visible to you. Clear skies — see you out there. OrbView Pro is an optional auto-renewing subscription, billed monthly or yearly. Payment is charged to your Apple ID when you confirm your purchase. Your subscription renews automatically unless you cancel at least 24 hours before the end of the current period.
