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.

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 Starlink satellite trains, Hubble space telescope, rocket bodies, comets, planets and many bright satellites.

Available Extensions (in-app purchase):

Radio Amateur Satellites: Track dozens of ham and weather satellites. Transmitter information and real-time Doppler frequencies.

Starlink and Famous Objects: Track SpaceX Starlink satellite trains, Hubble Space Telescope, rocket bodies, bright satellites and more.

Comets and Planets: Track all planets. And track comets as they come closer to earth and become bright enough to see.
