An iTouch is a line of affordable smartwatches and fitness trackers designed and marketed by iTouch Wearables. However, the term "iTouch" is also commonly used to refer to the iPod Touch, a discontinued line of iOS-based mobile devices designed and marketed by Apple Inc. . The iPod Touch can be used as a portable media player, a handheld gaming device, a digital camera, a web browser, for email and messaging, and more. It runs on iOS, the same operating system as the iPhone, and includes Safari, Google Maps, a Mail app, apps for Music and Videos, and several more. Users type on a virtual keyboard displayed on the screen, and can buy and directly download music, videos, and third-party software from Apples online stores. iPod Touch models were distinguished by storage space and color, and all models of the same generation typically offered identical features, performance, and operating system upgrades. An exception is the fifth generation, in which the low-end (16 GB) model was initially sold without a rear-facing camera and in a single color.

In summary, an iTouch can refer to either a line of smartwatches and fitness trackers by iTouch Wearables or the iPod Touch, a discontinued line of iOS-based mobile devices designed and marketed by Apple Inc.
