定数計算ができる

iOS18からCボタンがなくなり、定数計算もできなくなったのが不都合でコチラを利用させてもらっています。
上記に加えレイアウトは変えられるし、使うたびに広告が出ることもないし、数ある計算アプリの中から見つけられてよかったと思っています。

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?
