I use GoodNotes 5 in conjunction with an Apple Pencil. It does a really good job of converting my rubbish handwriting into usable text.
I like the look of Good Notes, do you use it in conjunction with the Mac app too?
Have you had any issues or problems with the iOS app?
Shame there isn't a free version with in-app upgrade to try it out.
No, I don't use the Mac app. I can't remember having any problems with the iOS app, it works really well.
