The story
Most of the Duo's launch reviews reached for the same two comparisons: the closed phone is the size of a passport, and the matte inner screen feels like paper. Passport is an attempt to make those two sentences literally true in your hand.
That meant caring about the paper more than the pixels. The cover takes the colour of the owner's own country's passport, measured from the real documents, with the word that country prints on the front. The pages are that country's visa paper, not a generic cream. Every country has its own stamp: its own shape, its own ink, the entry word in its own language, struck slightly crooked because real ones are. None of it copies an actual border stamp. Pages turn like paper rather than sliding.
Passport is a solo project from Slovakia, built on the iOS 27.1 Duo APIs, made to launch with the phone.
