Ask HN: How do make use of your apple pencil?

I'd love to make more use of my apple pencil but have to admit I've been constantly frustrated with the apps available on iOS.

While coding I often make rough sketches on sheets of A4 paper. I've always liked drawing, and find visually encoding information really important.

I'm often frustrated that it's hard to quickly export sketches/notes to other apps I might be working with. I feel like there should be better workflows/solutions available but perhaps I just haven't found them.

Does anyone else have this kind of challenge? Or have insights into how they make productive use of their iPad and apple pencil??
