Since everyone has a different workflow and personal preference, we don’t recommend a specific stylus. But if you’d like an idea of where to look, here is a list of the industry standards. We support each of them.
 
Adonit Styli (Pro, Pixel etc.)
 
Wacom Styli (Bamboo series, Intuos)
 
Apple Pencil (works only with the iPad Pro and supported iPads)
