Notability offers built-in palm detection and variable-width ink that work with any stylus and your fingers. As a result, you can use bluetooth styluses for basic writing in Notability. At the moment, though, the app doesn't support features like pressure-sensitivity or hardware buttons for styluses other than Apple Pencil. We don't plan to support more bluetooth styluses for now, but that's on our list of ideas to keep in mind for the future.
