Widgets are created by the app developer, so not all apps have widgets. For example, a weather widget provides up-to-date weather information, or a tap on a note widget opens a new note. Widgets can also be added to your Lock Screen, and for Apple users, the Today View. A widget usually appears on your Home Screen, and is an expansion of an app providing information without having to open the app, or gain quick access to an option within the app. The first widget appeared around 25 years ago. Widgets are all the rage now, but they are not new.
