Frequently Asked Questions

Can I turn off Apple Pencil pressure sensitivity in OneNote for iPad?

Currently, Microsoft OneNote for iPad does not have a built-in setting to disable pressure sensitivity for the Apple Pencil. You can submit feedback through the app's settings menu to request this feature in future updates.

Why does my Apple Pencil work fine in Word but act glitchy in OneNote?

Different applications use different rendering engines for digital ink. OneNote's specific integration with iPadOS pressure sensitivity can sometimes experience software glitches, whereas Word handles Apple Pencil inputs differently, which is why the thickness issue might not appear there.

Could my Apple Pencil tip cause handwriting to become thick randomly?

Yes, a loose, damaged, or worn-out Apple Pencil tip can occasionally send erratic pressure signals to the iPad's digitizer. Try carefully tightening or replacing the tip to see if it stabilizes the stroke thickness in your notes.
