Widget: Definition & explanation

Widgets are compact app extensions placed directly on the home screen or in a dedicated widget overview. Unlike an app icon, which only serves as a launch point, widgets display real, live data — the time, the next calendar event, current weather, or battery status. Many widgets are interactive too: you can pause music, add a note, or check off a reminder without opening the app. Technically, a widget accesses its app's background data through a defined interface (API) and refreshes automatically at set intervals or triggered by events. Android has long offered flexible widget support with freely resizable sizes, while iOS only introduced widgets with iOS 14, initially with limited interactivity. You typically add, move, or resize widgets by touching and holding the home screen. They're especially useful for information you need at a glance often, such as appointments, weather, fitness data, or news headlines. Some manufacturers also combine widgets with stacking features, letting multiple widgets rotate in the same space.
