A stylus pen is a pen-shaped digital accessory designed for use on touchscreen devices such as tablets, iPads, smartphones, and touchscreen laptops, offering more precise control than using fingers alone. It is commonly used for drawing, handwriting, note-taking, graphic design, editing, and navigation, making it popular among students, artists, and professionals. Modern stylus pens often feature fine tips, palm rejection, tilt sensitivity, rechargeable batteries, and magnetic attachment support for a smoother and more natural writing experience. Many models are compatible with multiple operating systems including iOS, Android, and Windows, though compatibility can vary depending on the device. ✍️📱
