Google Maps has been updated to properly support the iPhone Duo, Apple's foldable, making it the latest major app to adapt its layout to the device's dual-display design.

According to MacRumors, the update lets the app fill both the inner and outer screens of the foldable iPhone rather than leaving unused space along the edges — a common growing pain for apps running on the new form factor. AppleInsider published a look at how the navigation app now renders across both panels, using the full canvas the hardware offers.

The update is a notable data point in the iPhone Duo's app-ecosystem story. Foldables live or die on third-party support, and when an app as widely used as Google Maps moves from letterboxed compatibility mode to a true dual-screen layout, it signals that major developers are treating the form factor as worth real engineering investment.

Maps joins a steadily growing list of apps optimized for the Duo since the device's debut, with mapping — where extra screen real estate directly improves the core experience — an obvious early win.
