About this app
Two Fold: Uno's Quest is a puzzle adventure from Smaat Pay LLC about Uno, a small round creature searching for his lost family. Each level exists in two versions: an Outer world and an Inner world. Moving Uno between them, and using what you find in one to clear an obstacle in the other, is the core of every puzzle. Along the way Uno rolls, throws stars, squeezes through gaps and learns to rewind time, and meets companions such as Momo, Pip, Bao and Blanko, while spiky rock creatures called Grumps try to keep him lost. The story spans hand-built chapters, with version 1.2 adding chapters 34 to 36, two new characters who stop time and open portals, a free tutorial and a pet park. Beyond the story there are two nine-level events ending in boss fights and an Endless mode with three tiers, plus customisation for Uno's hats, outfits, fur and eyes, some unlocked only through play. Game Center leaderboards cover levels, events and Endless runs. The game is free to download with levels 1 to 17 playable at no cost; the rest of the story unlocks with a single one-time purchase, with no subscription or ads. It is aimed at children and adults alike, and it also runs on other iPhones and, since version 1.2, iPad. On iPhone Duo, the two worlds map to the device's two displays.

How it uses iPhone Duo
According to the developer's App Store description (current as of version 1.2, October 12, 2026), Two Fold is built specifically for iPhone Duo. The Outer world is what you see on the outer display with the phone closed, and the Inner world appears when you unfold it. Folding and unfolding shifts Uno between the two. On iPhones without a fold, rotating the phone switches worlds instead. DuoDiscover has not yet tested Two Fold on an iPhone Duo.
