TIER 1 — The top-quality tier of the Large screen app quality guidelines.
APPS DIFFERENTIATED FOR LARGE SCREENS create a user experience not possible on small screen devices.
Large screen differentiated apps make multitasking and drag and drop convenient and simple. Differentiated apps support the unique features of foldable devices, like tabletop mode, for a user experience other types of devices can't match.
External keyboard, mouse, and trackpad support are on par with desktop computers. Comprehensive stylus support makes the stylus an integral part of the device.
