That's an incredible experience. Thank you, NASA & the Crew in the station. Thank you for looking after us in 0 gravity. Every day I run out in to the cold freezing night just to see the ISS & I smile at it & waveπ. Love you crewππππππ

Great app, just purchased a year subscription. Makes it very easy to find when the ISS is passing for an attempted QSO. I'd give it a fifth star if it had an offline mode for use in locations with spotty/no cell service, very common here in Canada!

Very comprehensive library of trackable objects. Great for Amateur Radio Satellite work. Thank you for adding the Tel star satellites to the database for Famous Objects.

This is an awesome app! It helped me see the ISS for the dirst time. Something I've wanted to spot for years.

Do not update. No more map. You can not see or track the ISS anymore. This app worked great for years and now it is completely useless.

Waste of money, very buggy and not all features work. I purchased the full bundle and regret it. The app doesn't work all the time for the extensions such as amateur satellites when selected, it will not show up. I reset the app, and it is worse as it has even less of the extensions showing than before, despite the settings to show the info correctly set. The live video feeds of course won't work as well. I am using a Samsung Galaxy S4 if that helps.

If I could rate this app lower I would. They recently changed to a subscription based model in addition to the modular pay for extension to show information you want model. I have been using this app for close to 2 years, I paid for the amateur radio satellite extension, now I'm not getting the info I paid for because I'm not subscribed. When you pay for something in an app you should get to keep it, or you should get your money back for functionality you bought, but they locked you out of
