Is there an app for ND-measurement?

Hi there,

I wonder if there's an app for a situation like this:

I have the Pocket 6K and a Sigma 50 1.4 lens and I want to shoot outdoors wide open at 1.4.
I have various ND filters here but sometimes it is try and error finding the right one.
Yeah, I know the math but just asked myself if there's an app for stuff like that.

Not much of an app guy myself, but here's something I use that can help.

Not quite what I was looking for...

It is a different way to solve the problem than requested, but...I do think it will help.
