ISS Real-Time Tracker 3D tracks and spots ISS, Tiangong, and Hubble Space Telescope


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 the next 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, along with ratings to help you select the best passes to view.


The app locates and tracks the International Space Station, Tiangong (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.

❝ Having used various other ISS trackers over the years, that have since been left behind due to the lack of development, it’s been great seeing the attention that’s gone into this one. Clean, easy to use UI, which doesn’t take long to navigate your way through all of the different options. I love the fact there’s a complimentary Apple Watch App too, which makes looking out for passes really easy! Good work, thank you!❞


❝ Absolutely a brilliant app. We're having a run of about 10 days with the ISS overhead. This app gives you good details of what time and what direction it will be traveling. 10/10❞


❝ Very nice update. New icons for the Apple Watch app, the globe looks good on iPhone and iPad, and the James Webb background is spectacular. In my opinion, still by far the best of the ISS apps!❞


❝ This app offers as much hard information about the ISS and two other orbiting bodies as anyone could want, presented in a logical and easy to use manner. The watch app works perfectly on my old Watch 5, and the iPhone version is a pleasure to use scientifically and also visually. Tech support is immediate, personal, and efficient. Among my many, many apps this one is at the very top. Five stars for sure!❞


❝ The most beautiful App I have downloaded.❞
