Ratings and reviews

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 sattilite 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

I used to love this app. I bought all of the extension so I could see everything. Recently, notifications have stopped working and when I open it it is only showing the ISS. I need to refresh it to see all of the extensions I paid for. The extensions then work for maybe one more day, then they stop. It seems to have started after the most recent update. I have sent emails, but no response. Sure wish you would fix this issue.

I finally looked into the short easy training. Now that i understand that it all means, i know exactly where to look for the ISSor what ever else i am interested in. Stuff i never knew about before this app. I actually pulled out my cell phone and took a few photos, hoping for at least a dot. Imagine my excitement when i saw a dot, zoomed in and actually have a photo of the iss even with the solar wings and all! I look up every time the sky is clear and some thats not so clear, nust to be sure.
