It worked, but it's not obvious how to use it
However, it's not clear what all of the functions do. The pictures in the app store show a button to get an owners manual and do troubleshooting, but my app doesn't have either button.
There doesn't seem to be any tooltips for the buttons so it's not clear how to use some of the features. For example, there appears to be a couple of memory buttons but I don't know how to configure them.
