Methinks you must have a tiny hand with no capacitance...! I have the same trouble with Penultimate as the previous poster - I touch the screen below where I'm writing and I either get a page turn or a mark or both. And the blasted permanent, complete, two-way sync is still there - so I've abandoned Penultimate for now. I'm using Notes Plus. Amazingly powerful, and easy to use. I used Notability for a while, but a student put me onto Notes Plus and I haven't looked back. Agreed, I invested in Notes Plus since Penultimate was crippled by Evernote. No subscription required to use what I once had backed up with Dropbox. Notes Plus is fantastic!
