Fantastic app
Thank you for updating this app, I was afraid it may be scrapped for iOS 11. I use this app all the time, it's simple, straightforward & fast.
Never Use a Wall Chart Again
This app has everything most engineers could want regarding hardness conversion. The built-in roundness correction is also a nice touch. The only deficiency I can see is that the Knoop and Vickers hardnesses are not explicitly stated as macro- or microhardness, although that is the case for ASTM A370 and I can't be too mad about that.

I was disappointed because the conversions did not match the values of the Wilson chart.
