Have you seen the International Space Station? It is visible like a bright moving star!
This is the easiest way to spot the station.

ISS Detector will help you to find out when and where to look for the International Space Station or Iridium flares. You get an alarm a few minutes before a pass. You will never miss a pass of the International Space Station and you will never miss the bright flashes of the iridium communication satellites. 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 comets and planets, amateur radio satellites and famous objects, like the Hubble space telescope or the Chinese space station Tiangong 2.
