Try an app that has a defined palm rejection area, like GoodNotes (there's a free version). You pull up a "screen" from the bottom where you can rest your palm. Or try a glove like someone mentioned. I made my own (it's not rocket science), but I guess I won't be using it in public.
You mean too fat, such that you can't see what you're doing? Yeah, that's a common complaint, and the reason some people use the Jot mentioned here, or the GoSmart.
Again, try GoodNotes. Some apps truly are more responsive than others.

Thanks, Tom. Will definitely try the App you recommended!
