# Made for Duo 雙屏

Fun app design for iPhone Duo, Apple's foldable — posts on Threads and X that
show an app across the fold and on both halves, hand-picked by the
harbormaster (Victor Lee, Berth №001), newest first. Never ranked, never
counted. A showing may point at its app on the sightings wall, or stand alone
(a concept, an app not out yet). The page: https://soloberth.com/duo
