App Review told me that my app can not be marked as a blood alcohol content calculator without the appropriate hardware. They refer to the expression "Promillewert", it is German and stands for "per mille value". They also referred to to the Guideline 1.4 (Physical Harm). Is the way how I used the words the problem or the app itself? My idea is to use the expression "Geschätzter Promillewert"/"per mille value estimation", but I do not want to miss the App Review again.
