Scribble

Scribble is a handwriting recognition feature developed by Apple for users of the Apple Watch, and later, iPad models that support the Apple Pencil. Text can be written into any text field and recognized on supported devices.

History
A simpler version of the Scribble feature first appeared with the release of watchOS 3 on September 13, 2016. It required a combination of the use of fingertip writing and scrolling through predictive text choices with the Digital Crown.

Scribble for iPads was introduced with the release of iPadOS 14 on September 16, 2020, initially with support for English and Chinese recognition. Support for French, German, Italian, Portuguese and Spanish languages is scheduled to be added with iOS 14.5, which entered beta testing in February 2021.
