Why Use a Stylus

Most people use a stylus to write notes to themselves on a touch screen, draw images, or make other notations on their phone or tablet. Artists often use stylus pens to draw animations or other artwork on laptop computers or tablets. Using a digital pen with a touch screen mimics using a pencil with paper, except the information is digitized and can be saved or shared.

As digital pens have become more popular, apps have sprung up to take advantage of their capabilities.

Support for Digital Pens

Many smartphones from manufacturers such as Samsung, Google, Huawei, and Xiaomi include stylus capabilities in their phones. In some cases, the stylus slides into a slot built into the smartphone for that purpose. For those that don't come with a stylus, you can purchase one separately and keep track of it on your own, assuming the device supports stylus input, which not every device does.

Many tablets also support stylus options. The Apple Pencil is available for certain iPad models. It can perform most of the same functions a fingertip can, only with more precision. Other tablets that support a stylus include Samsung's Galaxy Tab S7, the Lenovo Tab P11, and Microsoft's Surface Go 2.

The device is also a popular accessory for use with touch-screen laptops, including Microsoft's Surface Pro 7, HP's Spectre x360, and the Dell Inspiron 13, among others.

In the world of digital pens, one size doesn't necessarily fit all. Although some stylus pens work with any touch-screen device, sometimes only digital pens produced by the laptop, phone or tablet manufacturer are compatible with their devices.
