Any good ideas please for a stylus with Penultimate or Notability on a mini4? I currently use a mini2 but have not found a decent stylus so far which is useful for writing and I am planning to get mini4 in the next month. The ones I have used are the Adonit Jot Pro, the Pogo and the Bamboo stylus, none of which are bluetooth, not sure if that would make a better stylus? The Jot Pro seems must accurate but they don't compare (naturally) to the Apple pencil on the Pro. Thanks.
