that is a great workaround.When I downloaded native apps, I subsequently put my iPhone into airplane mode and then tried to open the app on my watch. If it opened, I took that to mean that it was truly native. Since non-native apps rely on the phone to do all of their processing, they shouldn't open at all while the connection to the phone is broken. At least, that's how I understand it.
I was hoping for an indicator. different app background color.
