CALCULATE WITH DYNAMIC ISLAND Start a Live Activity in the app, switch to another app, then touch and hold Dynamic Island to expand the keypad. Enter numbers manually while viewing a bill or shopping list. Dynamic Island requires a compatible iPhone; other supported devices can display the Live Activity on the Lock Screen. INTERACTIVE HOME SCREEN WIDGETS Medium and large widgets support direct input without opening the app. The current expression and result are shared across the app, widgets, and Live Activity.
