A stylus is a small, pen-like tool used for writing or drawing on touch-sensitive screens, such as those found on tablets and smartphones. It allows for more precise control compared to using fingers, making it ideal for tasks like note-taking, sketching, or navigating apps. Styluses can be made from various materials, including plastic and rubber, and some even have pressure sensitivity for a more natural drawing experience. Many styluses are designed to work with specific devices, such as the Apple Pencil for iPad or the Samsung S Pen for Galaxy Note phones. They can enhance productivity and creativity, especially for artists and professionals who rely on digital tools for their work.
