Apple Pencil and Apple Pencil 2 are the two connected styli that work with Paper.
Finger Setting
Use the Finger dialogue to select an action for your finger when using Apple Pencil. Tap on the Settings icon top right, then "Canvas Settings", then "Stylus Settings", and then "Finger Settings".
The Cut option is only available for users who have access to the Cut Tool. Paper Pro subscribers have access to Diagram, Cut and Fill tools.
Apple Pencil
Apple Pencil cannot be connected through Paper. You must connect Apple Pencil to your iPad Pro, and then Apple Pencil will work in Paper without any setup. Here are Apple's instructions on how: Pairing Apple Pencil with your iPad
Apple Pencil 2
Paper 5 supports the double-tap gesture for Apple Pencil 2. Just choose the behavior you’d prefer directly in your device's iOS Settings:
- Switch to the eraser
- Switch to the last used tool
- Show the color palette
Pencil by FiftyThree
Support for Pencil by FiftyThree was discontinued in 2019, but it will continue to work as a passive stylus.
