Good stylus for iPhone X?

I use the app Sketchbook (by Autodesk) on my iPhone X to kill time on public transport. I feel like it could be better using a stylus rather than my stubby fingers.

It is surprisingly difficult to find information pertaining to iPhone X compatibility. Some companies say their stylus works for iPhone 6 or 7 and newer, but the product is a few years old and I don't know if that information is dated or current.

The only one I could find that definitively says it works with iPhone X is the Bamboo Tip, but unfortunately that stylus is not an active stylus, therefore does not detect pressure sensitivity, which is a feature I would like. The other Bamboo styluses are vague in their description, only saying it works with iPhone 6 and newer, while not definitively saying it works with iPhone X like the Tip.

So long story short, any designers/illustrators out there know of a good active stylus for the iPhone X? Something that works well with sketching/drawing apps? Thanks.
