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 posture, 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.
Do's and don'ts
- Think big
- Design custom layouts and behaviors
- Make your app different from anything else
- Settle for less
- Design for just one or two device types
- Let your app be unremarkable
