Hm. That seemed unnecessarily contentious. We were largely in agreement. Yes, the german one is using more lax standards, as I was saying, hopefully not too lax, but yes, the colours indicate entirely different standards. And yes, I think a simple solution would be to use the colour of your home country that you are used to. Presumably if you moved, you could just learn the standards of your new country. A consistent standard that you can rely on in your phone when on a trip to another country definitely seems more useful if you are actually relying on this iOS app. It could be a simple app pref, a little toggle switch..
