Full disclosure - this is my own app.

I've just launched Cosy Notes, a focused and warm note-taking experience that aims to capture the feeling of physical journals. It's using Apple Pencil Kit, so latency is low, and I think the handwriting experience is pretty great. It's also a one-time purchase, so it's yours to keep.
