Fine but improvements can be made
It’s a great calculator, but when using it in slide over while using apple pencil, the scribble bar blocks out the bottom row. As a result, the 0 button and the = button are blocked and unusable. If there is a way to get rid of the scribble bar without disabling scribble that I do not know of, I would gladly implement that. However, since I usually use the app when I am lazy to get my calculator when doing homework, this rather kills the functionality. I hope that there can be a way to scale the slide over view while using the Apple Pencil so that all digits can be used.
Underrated
