Using a Pressure-Sensitive Stylus

PDFpen supports the following pressure-sensitive and bluetooth styluses:

• Apple Pencil
• Pencil by FiftyThree
• Jot Touch and Jot Script from Adonit

Once configured, PDFpen will work with your pressure-sensitive stylus while using the Scribble tool in markup mode. For a stylus that supports pressure, pressure of the stylus varies the strokes drawn providing a remarkable hand-crafted look to your drawing and writing. If your stylus supports pressure and you don’t see that, check connection settings using the setup steps below.

1. Tap “Tools”  > “Settings” > “Stylus”
2. Select a stylus from the list
   For bluetooth pens turn on bluetooth in the iOS Settings app of your iPhone or iPad
   For older Jot Touch pens you’ll need to pair the device with the pen in the iOS Settings app
   For Jot Script pens use the Jot Touch settings, though the Script does not include pressure-sensitivity
3. In the “Stylus” settings select a handwriting posture
   This is used to filter out touches from the hand when using a pressure-sensitive stylus that does not have that capability built-in. There may be occasional mistakes, Undo  is in the upper left.
4. Tap the scribble tool to start writing

Once a stylus is setup, notice the stylus button in the editing bar. With a bluetooth stylus it indicates whether the stylus is connected or not. If disconnected, hold down the buttons on the stylus to turn it on and connect.

Tap the stylus button to show additional connection settings.

PDFpen also supports the stylus buttons. Depending on the stylus the button function is configurable. By default a single button will change color, and a second button performs undo.
