Special Inspection levels not supported

Nice calculator for a shortcut to not having the ANSI tables available. However, the tool doesn’t include the Special Inspection levels. It only has the General Inspection levels :-(

Developer Response ,

Thank you for feedback. For the full version of the ANSI Z1.4 tables please look at the non-lite version of the app: Sampling Calculator (https://apps.apple.com/us/app/sampling-calculator/id1304811062)

Perfect for what normal II inspection

We only do level II normal inspections. This app is perfect for that.
