Widgets come in multiple sizes, and people can visit the widget gallery to search and preview sizes. They can place them anywhere on the Home Screen in iOS and iPadOS, or in the macOS Notification Center, to access important details at a glance. In iOS and iPadOS, they can also add Smart Stacks — sets of widgets that use on-device intelligence to surface the right widget at the right moment based on factors like time, location, and activity. Even widgets that haven’t been manually added are suggested in Smart Stacks based on past behavior and on intent donations for new events. In addition, you can use TimelineEntryRelevance to rotate your widget to the top of the stack when it’s relevant to the user.
