Receive an Notification when the ISS is overhead!
This works great, when you receive a notification look up at the sky and you'll see a bright light in the sky (International Space Station). The light is usually visible even in the day time. P.s. You can also view the ISS as a live steam to get an aerial view of your location as it passes overhead! > http://www.ustream.tv/service/live-iss-stream
