Ruler no good. No response – iHandy Carpenter Review

This is a beautiful app, and most of the tools are great. As many, many users have said here, though, the ruler is grossly inaccurate in recent larger screens. (IPhone 7+ here). If you can't fix it, will you please respond? Otherwise, Apple should pull it from the App Store.
