Apple Pencil apps

I’ve just bought an Apple Pencil 1st generation for my iPad Air. It will be used primarily for note taking and I’m wondering what is the best app for this type of use, of course free is best!

There does seem to be an awful lot of apps out there, some paid for some not. I have watched quite a number of YouTube videos on this topic. The top three seem to be Notability, Goodnotes, OneNote. Is Scribble an app or something to make the pencil do he business?

I would need to have he capability of placing accents on various letters e.g.:  á, é, í, ó, ú. 

When reading reviews Notability seems to come out on top but it’s a yearly subscription £10.49 in the second and so on

I’d be interested in hearing your views, especially those who use this type of app on a regular basis
