In the latest versions of the apps, 2018 iPad Pro users can now take advantage of the new Apple Pencil's double-tap functionality to switch between drawing tools, activate the color picker, and zoom in and out of the canvas.
The double-tap gesture can be set to one of the following options in the Settings app under the Adobe Sketch or Adobe Draw menus:
- Switch between brush and eraser
- Switch between current and last used brush
- Activate the color picker
- Zoom in or out
Check the updates tab of the App Store for version 4.7 of each app.
