Everything in orbit, live, in your hand. OrbitWatch tracks more than 18,000 real satellites and pieces of space debris using open orbital data, computed on your device with the same SGP4 math used by professionals — then turns it into an experience the whole family will fight over. ONE CONTINUOUS UNIVERSE Pinch from street level to the stars. Start at your own neighborhood in real satellite imagery, zoom out through the swarm of satellites circling Earth, keep going to a solar system where every planet sits at its true position today, then out to the Milky Way and our Local Group of galaxies — every stop labeled and explained for curious kids (and adults). WHAT'S ABOVE YOUR HOUSE — RIGHT NOW • My Sky lists every satellite above your horizon this second, with direction and distance. • 48-hour pass predictions for the ISS, Tiangong and your watchlist — with a VISIBLE badge when a pass will be sunlit against your dark sky, so you can actually step outside and see it. • Tap the bell and get a notification 10 minutes before a pass rises. POINT AT THE SKY (AR) Open Sky View and hold your phone up: satellites, their motion trails, the Sun, the Moon with its real phase, the planets and the brightest named stars appear exactly where they are in your sky, over your live camera. A compass ribbon keeps you oriented, and the FIND THE ISS arrow guides your hand until the station enters your view. STORIES THAT ACTUALLY HAPPENED Fly to the real debris of the 2009 satellite collision and watch it reenacted. See the missile tests that made the biggest debris clouds in history. Visit Hubble, the GPS constellation with its relativity-corrected atomic clocks, Starlink, Tiangong — plus a live feed of what launched in the last 30 days, in 2025, and in 2026, and what's about to fall back to Earth. VISIT THE PLANETS Tap any planet to fly to it: 8K NASA-imagery surfaces stream in as you zoom — skim Olympus Mons on Mars, or see Venus's hidden surface through radar. Kid-friendly fact cards on every world. BUILT TO RESPECT YOU No accounts. No ads. No tracking. Your location never leaves your phone — every calculation happens on-device. Orbital data courtesy of CelesTrak; textures from NASA and Solar System Scope. Whether you're a space nerd, a parent with a curious kid, or someone who just saw a strange line of lights in the night sky — OrbitWatch tells you exactly what's up there.
