About & Pics


Have you seen the International Space Station? It is visible with the naked eye!
This is the easiest way to spot the station.
ISS Detector will tell you when and where to look for the ISS. You get an alarm a few minutes before a pass. You will never miss it. ISS Detector will also check if the weather conditions are right. A clear sky is perfect for spotting. The Chinese space station Tiangong 2 are also tracked.

Extensions will enhance the functionality of ISS Detector. With an in-app purchase you can add many famous satellites and amateur radio satellites. See the Hubble space telescope, rocket bodies, Vanguard 1 and many bright satellites.

Available Extensions (in-app purchase):
Radio Amateur Satellites: Track dozens of ham and weather satellites.
Famous Objects: Track Hubble Space Telescope, rocket bodies, bight satellites and more.

 Free in iOS App Store
