Sketch only supports pressure-sensitive styluses in iPad versions of the app, so on an iPhone you would have to use a capacitive (a pen with a rubber tip) stylus.
Hope knowing that helps.
Thanks for your recommendation! I searched for capactive stylus and saw that some have very rounded tips, while others have a distinct finer point. I wondered if the rounded tips offer less precision. Do you know if one is better than the other?
You know... I've always used the rounded tips and it sure seems like a finer tip would be easier to use. If I had to buy one tomorrow, I would get one with a finer point.
But, what you could do is find some that are super cheap and try a couple of different tips to see which you like better.
Not sure how helpful that is.
Thanks for your advice. You've been very helpful. Now I have some things to think about.
