Most intuitive satellite tracker to see International Space Station (ISS), Starlink flares, Tiangong and others using AR, augmented reality technology.

This simulates a way of satellite on top of reality through the camera and map.
Not only satellites, planets, fixed stars, galaxies, black hole, spacecrafts (Voyager1, Voyager2, Starman, New Horizons etc.) and even world cities are shown as if earth was transparent.
Displaying geostationary orbits will also be very helpful when you adjust a parabolic dish antenna.
It connects Twitter too. So you can share excitements of finding satellites and weather conditions with others all over the world.

Apple Watch app and "Today" widget are also available. They show simple lists of satellites' passes.

LITE edition with Ads and without Iridium flares is available.


* Simulates way of satellite on top of the camera view and the map.
* Displays orbits and current positions of satellites and users' messages on the world map.
* Satellite prediction calendar
* Displays fixed stars, galaxies, a black hole, spacecrafts, geostationary orbits and cities through Earth over the camera view (You can choose visibilities of each layers)
* Displays Iridium flare centres on map
* Supports offline
* Newly launched satellites will be added automatically
* Sends notification 1 hour before each pass

Continued use of GPS running in the background can dramatically decrease battery life.

What’s New

Version 2.11

For better experiences, we made some improvements:
* AR view starts as soon as the first pass is found, without waiting for all results of orbital calculations.
* Lines on AR, map and sky chart views are smoother.
* Background activities are optimized.
* You can clear cache files (the menu is added to the Settings screen).
Bug fixes:
* Fixed a problem related to launching the app by the Today widget or web links.
* Fixed a crash when selecting selecting 10deg or below in "Elevation threshold" selector.

I really enjoy introducing new people to the viewing of an overflight of the ISS.

Great app

Great augmented-reality visible-pass prediction app for the ISS and some others. Excellent support and fast response to questions.

Works on iPad Mini, but not iPod

Tried this app on my iPod, didn't work at all. Tried it on my iPad Mini, works amazingly. Great app for iPad users, good tracking and allows me to see relatively nearby (pretty sure it is showing nearby) galaxies as well as satellites and most importantly, the ISS. Not bad, and as I've said, it didn't work for me with my iPod, but it may work for others.
