I have bought and tried most of the available apps that "look reasonable" (to me, of course). As of now, my "go to" app is Good Notes. I find it to be the all around best for handwriting and annotating pdf's. But Note Anytime has what seems to me to be the best zoom window. You can move it anywhere up and down the screen and change its size as desired. But when you hit return at the end of the line, the point it returns to isn't as precisely controllable as is Good Notes. At one time, back in the early days of iPad 1, I used Note Taker HD, but its zoom window leaves a lot to be desired. Okay, enough for an introduction. My reason for initiating this thread is curiosity as to what others are using for handwriting and why. Would you be willing to share your experience? Passing references to styluses and/or pdf file annotation apps would also be of interest, but I hope we can keep the focus on HANDWRITING. Hope this works for you.
