Hello there!
I have an iPod touch. When I launch SignalScope without an internet connection active, it gives an error saying it can't connect to the AppStore. I am not sure why it does this but this error is a bit annoying as it happens every single time I launch the app and I need to click OK to close the error message. Strange because I have the in-app purchase display switched off (already bought the octave analyzer upgrade but do not need the others).
I sincerely hope you can improve your wonderful software so it doesn't raise this error.
Thanks!
