Solid app that could do with a few enhancements

Solid app though a bit over wrought for its intended purpose. Ad-free cost is also not clear as it seems purchasing on Mac App Store does not provide IOS version ?

WEIGHT Conversion

1) My unit converter does NOT show weight conversions: why?

2) 11/25/25
Suddenly keys started making sound when i type numbers. I don’t want sound and don’t know what to do!

Do you check these notes?
