Fun iPhone Duo Apps: Best Indie Games, Toys, and Creative Apps
The best fun iPhone Duo apps right now are Deck-Man, TypeDraw, Tiny Computers, Toastie, Orisuji, and Marbles Unhinged. Each one is built around the Duo's hinge, two displays, or tent and book poses. Behind them is a second wave of open-source experiments and hackathon prototypes that are not on the App Store yet.
This guide covers what each app does, who made it, and where to find it. Every app below links to its App Store page, its creator's post on X, or its source code.
How we picked these fun iPhone Duo apps
We looked for apps and projects made for the Duo's two displays, and we included only ones we could link to a primary source: the App Store, a creator's own post on X, a GitHub repository, or the developer's site. Aggregator sites such as FoldHunt were used to find leads only. We checked everything on October 25, 2026.
We have not tested these apps on an iPhone Duo. Prices come from App Store pages. Apps that are in beta, in development, or only shown in a simulator are labeled as such. Apple's Made for iPhone Duo list is covered in our guide to the best iPhone Duo apps.
