I SS Spotter


I love this app because it gives me very accurate information about the tracking of the International Space Station. It also lets me set up alarms to notify me when the ISS will be visible from my location, making this app very useful to the novice astronomer.
The best thing is that it is free for all to use. I like it so much that I made a donation to the developer and I hope that they will have many further improvements to this app.

Tremendous app for space inspiration

You can schedule an alarm to let you know that the space station is coming into view. I have used it twice so far with my son. It is incredibly accurate and makes spotting the space station easy. As an Apollo era person, this allows me to share some of the wonder of space with my child. Highly recommended!

Easy. Accurate. Fun.


This app provides the date, time, and specific elevation to locate the ISS as it orbits the Earth near your location.
So easy, accurate, and fun you'll wonder how you've never randomly spotted it going by on your own since its launch nearly 20 years ago.
