Hi,
our app is already on the App Store, but we were rejected during the last review. The app is available here - https://itunes.apple.com/us/app/alcoholmeter-alcohol-check/id739177171?ls=1&mt=8.
The reason from the review team is that our app is marketed as a blood alcohol content calculator but does not have associated hardware to perform these calculations accurately.
Our calculations are based on the Widmark formula which is available here - https://www.wsp.wa.gov/breathtest/docs/webdms/Studies_Articles/Widmarks%20Equation%2003-07-2002.pdf. So the app itself does not need any associated hardware.
We do not understand where is the problem and why the app was approved multiple times and now not. The last update did not change nothing important in the app so it is not the problem. We sent all the information (Widmark formula etc.) to review team and asked them, in which way we break 1.4 guideline rule. But we received this - We are not able to provide feedback on app concepts or features...
Can anyone help us to understand where can be a problem?
