Handwriting apps are digital tools designed to help users write by hand on their devices, such as tablets and smartphones. These apps often simulate the experience of using pen and paper, allowing users to take notes, create sketches, or annotate documents. Many handwriting apps support various writing styles and can convert handwritten text into typed text, making it easier to share and organize information. These applications are popular among students, professionals, and artists who prefer the tactile feel of writing by hand. Some well-known handwriting apps include GoodNotes, Notability, and Microsoft OneNote. They often feature customizable pens, colors, and paper types to enhance the writing experience.
