A smartwatch is a computerized wristwatch in which functionality is extended beyond timekeeping, often with features comparable to those of a PDA. This is a wristwatch that does more than just tell the time. It has an operating system and can run apps. This may include GPS, Bluetooth connectivity, WiFi capability, and more. Many smartwatches also include a native touchscreen interface for daily use and come with associated smartphone applications that allow the user to manage the watch. Early smartwatches could perform tasks such as calculation, digital time telling, game-playing, and translation. Smartwatches from 2010 onwards have much of the same functionality as smartphones, including mobile applications, mobile operating systems, and Bluetooth/WiFi connectivity. Some smartwatches can function as portable media players, and some have mobile cellular functionality for making calls.
