THE APP FOR SPACE ENTHUSIASTS

ISS Real-Time Tracker 3D is a unique, beautiful, and highly popular space station spotting and tracking app for iPhone, iPad, Apple Watch*, and Mac**.

ISS Real-Time Tracker 3D tracks and predicts flyover passes for the three most significant artificial objects in Earth Orbit.

The app tracks and predicts passes for the following:

• International Space Station
• Tiangong space station
• Hubble Space Telescope

Get flyover pass predictions and detailed viewing data for up to 30 days. Then, set alerts in your calendar with one tap so you'll never miss a flyover. The passes table provides all the information you need to spot the station and ratings to help you select the best passes to view.

The app locates and tracks the International Space Station, Tiangong (the Chinese space station), and the Hubble Space Telescope in 3D and real-time on a beautiful photorealistic 3D model of the Earth and the ISS on an animated interactive map of Earth with a ground track overlay.

The interactive 3D globe is fun to explore and educational, too.
