Widgets on iPhone are mini versions of apps that provide information at a glance or quick access to various tasks without having to open the full app. They can display current information such as todays headlines, weather, reminders, battery levels, and more. Widgets can be added to the Home Screen, Lock Screen, or Today View, and can be interacted with directly without opening the app. Users can customize and edit widgets to display the information they want to see, and can also create widget stacks to save space on the Home Screen and in Today View. To add a widget to the Home Screen, users can touch and hold an empty area on the Home Screen until the apps jiggle, tap the plus sign in the upper-left corner, select a widget, and then tap Add Widget.
In summary, iPhone widgets are a convenient way to access and view important information from various apps at a glance, and they offer users the ability to customize their Home Screen and Lock Screen to suit their preferences.
