Recommended Styluses
We recommend using an Apple Pencil for best results. We unfortunately no longer support third-party styluses, and we cite why in our blog post: Astropad's Break-up with Third-Party Styluses.
To give you a brief look into this, however, we will quote a portion of the blog post that sums up our reasoning here: "If the stylus you’re using has performance shortcomings, your overall experience in Astropad isn’t going to be as smooth as we built it to be. In our extensive QA testing, we found that pressure sensitivity in third-party styluses was not as refined as the Apple Pencil."
