Ratings and reviews

my previous review was invalid because my compass was not calibrated. i was told to calibrate and now we're all good again. actually this app kicks butt you can track many satellites and objects using this app. Just make sure you calibrate your phone! one downside is that it no longer provides the sattilite frequency which was really helpful but only a Google search away.

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.
