ISSINFO

Track the Space Station Live

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Explore a rebuilt 3D Earth, watch Starlink satellites live, tour the Solar System, find Sun and Moon transits, and set wake-up alarms for passes. Follow the International Space Station in real time, plan your next sighting, and explore the spacecraft and worlds beyond Earth. ISSINFO combines live orbital tracking, accurate pass predictions, weather insights, and immersive 3D experiences in one app for iPhone and iPad. TRACK THE ISS AROUND EARTH - Follow the ISS on standard, satellite, hybrid, and photorealistic 3D globe views. - See the station at its true orbital altitude above a realistic day and night Earth. - View current and historic orbit paths, city lights, altitude, speed, visibility, and the location below. - Track Tiangong, Hubble, Vanguard 1, Landsat 9, and NOAA-20, each with its own position and orbit. PLAN YOUR NEXT SIGHTING - Find upcoming passes for your location. - Check start time, direction, maximum elevation, duration, visibility, and viewing quality. - Use cloud cover forecasts to decide whether the sky is worth watching. - Explore detailed sky path diagrams and maps for each pass. - Point the AR camera toward the sky to help locate the ISS. CHOOSE HOW YOU ARE ALERTED Set a standard notification before a pass, or choose a wake-up alarm for a pass you do not want to sleep through. Select an alarm at the start of the pass or from 5 to 60 minutes beforehand. With permission, alarms can sound through Silent Mode and Focus with a full-screen alert. STARLINK VISUALISER Watch thousands of Starlink satellites move around a photorealistic 3D Earth. Filter the constellation by orbital shell, use tapered trails to read direction, and select individual satellites for live altitude and speed. Positions are propagated on your device using SGP4. TRANSIT FINDER Discover rare moments when the ISS or Tiangong crosses the Sun or Moon. Search around your location, view the ground centerline, see exactly where to stand, inspect transit diagrams, compare the view from home, and open driving directions to the best viewing spot. SOLAR SYSTEM SIMULATOR Travel through a detailed 3D model of the Solar System using real planetary positions. Move through time by up to 50 years, switch between visual and true scale, inspect planets and moons, and explore a GPU-rendered asteroid belt. FOLLOW ARTEMIS AND THE CREW Track NASA Artemis missions through live and historic deep-space trajectories, mission phases, itineraries, imagery, and phase notifications. You can also meet the people currently in space through crew photos, biographies, missions, and spacecraft details. ISSINFO Pro includes Starlink Visualiser, Transit Finder, Solar System Simulator, 30 days of pass predictions, multi-satellite tracking, cloud forecasts, AR tracking, pass notifications, and wake-up alarms. Built for space enthusiasts, photographers, educators, and anyone who has looked up and wondered when the ISS will pass overhead. ISSINFO is an independent app and is not affiliated with NASA, ESA, SpaceX, or any government space agency.

Version 1.5 brings new ways to track Earth orbit, plan rare sightings, and explore the Solar System. IMPROVED 3D GLOBE - A rebuilt photorealistic Earth with realistic daylight, night-side city lights, clouds, and atmosphere. - The ISS and other satellites now appear at their true altitude above Earth. - Thin satellite-to-surface lines show exactly where each spacecraft is overhead. - Solid past and dashed future orbit paths make each satellite's direction easier to understand. - A clearer satellite picker and a refined white ISS marker with an animated green pulse. STARLINK VISUALISER - Watch thousands of Starlink satellites move around a live 3D globe. - Filter the constellation by orbital shell. - Read direction from tapered motion trails and inspect individual satellite details. TRANSIT FINDER - Find upcoming ISS and Tiangong crossings of the Sun or Moon. - View centerline maps, stand-here locations, transit diagrams, and viewing geometry. - Open Apple Maps or Google Maps directions to the best viewing spot. - Larger and more stable Transit Details on iPad. SOLAR SYSTEM SIMULATOR - Explore real planetary positions in a photorealistic 3D scene. - Travel through time by up to 50 years. - Switch between visual and true scale. - Inspect planets, moons, and a detailed asteroid belt. PASS ALARMS - Keep standard pass notifications or set a wake-up alarm for selected passes. - Choose the pass start time or a warning from 5 to 60 minutes beforehand. - Alarm settings are saved and reconciled with the system alarm list. - The redesigned alarm panel fits without scrolling on iPhone and iPad. This update also includes interface refinements, performance improvements, and bug fixes across iPhone and iPad.
